Cancel Dexcom: Easy Method

What is Dexcom

Overview

Dexcom is a company that manufactures continuous glucose monitoring (CGM) systems, including sensors and transmitters used by people with diabetes to track glucose levels in real time.

The product range includes ONE+, G6 and G7 sensors, subscription plans for regular deliveries, and related apps and accessories.

How Dexcom is sold in New Zealand

Dexcom products are available via retail channels in New Zealand and, for eligible patients, through Pharmac-subsidised programmes from 1 October 2024.

Purchases can come from Dexcom web stores, authorised retailers, or app-store purchases for some software components.

How to cancel Dexcom

Cancel an order before shipment

• Sign in to your Dexcom online account on the web store used to place the order.
• Locate the order and select the cancel option if the order has not yet shipped.
• Save screenshots or confirmation emails that show the order was cancelled before shipment.

Cancel after shipment or cancel a return

• If the order has already shipped, notify Dexcom in writing or by phone within 14 days of delivery to request a return (products must be unopened and sealed).
• For ONE+ subscriptions, cancel at least 2 days before the next scheduled shipment to avoid being charged and shipped.
• For app purchases or in-app subscriptions, manage cancellations and refunds through Apple App Store or Google Play, not directly through Dexcom.

What happens when you cancel

Account and subscription effects

When you cancel a pending order, the shipment is stopped if it has not left the warehouse and you retain access to your account and historical data.

For subscriptions, cancellation prevents future shipments but does not usually refund past fulfilled shipments unless eligible under refund policy.

Data and device access

Cancelling a purchase or subscription does not automatically delete your app data or device records unless you request account deletion through the app or support.

Continue to have access to any data stored locally on devices or in linked cloud accounts until you take additional action.

Will I get a refund?

Dexcom returns policy (purchase conditions)

Dexcom regions (EE/UK terms) allow cancellation and refunds within 14 days of delivery if products are returned unopened, sealed and undamaged.

Refunds are typically issued within 14 days of Dexcom receiving the returned goods and may exclude original delivery costs depending on the terms that applied to your purchase.

New Zealand exceptions and practical points

• New Zealand law does not provide an automatic 14-day change-of-mind right; refunds for change of mind are at the seller's discretion.
• If a product is faulty, the Consumer Guarantees Act (CGA) entitles you to a remedy (repair, replacement, refund or compensation) regardless of Dexcom’s stated return policy.
• App store purchases (Apple or Google) must be handled through those stores for refunds; Dexcom disclaims responsibility for app-store refund processing.

Dexcom plans and pricing

Retail prices (NZ)

Subsidy and funding note

From 1 October 2024, Pharmac provides subsidies for eligible patients: example prices include Dexcom ONE+ at NZ$81.00 per sensor and other funded options.

Funding amounts are ex-manufacturer and may exclude GST; check Pharmac for eligibility and up-to-date subsidised pricing.

Your consumer rights in New Zealand

Consumer Guarantees Act (CGA)

Under the CGA, goods must be of acceptable quality, fit for purpose and match their description.

If a Dexcom product is faulty, you are entitled to a remedy: repair, replacement, refund or compensation depending on the issue and its severity.

Change-of-mind and retailer policies

• NZ law does not require retailers to provide refunds for change of mind; voluntary return windows (e.g., 14 days) are seller policies, not CGA rights.
• If a seller offers a voluntary returns policy in NZ, that policy applies in addition to CGA protections, not instead of them.

Customer experiences

Positive feedback

Many users praise Dexcom for high-quality CGM technology and accurate readings, especially long-term G6 users who find accuracy reliable.

Some reviewers noted improvements in newer generations (G7) such as size and warm-up time.

Common complaints

Reported issues include sensors sometimes failing before full lifespan, occasional inaccurate readings, and transmitter problems.

Customers often report dissatisfaction with customer service response times, inconsistent replacements and difficulties with app or registration behaviour.

Documentation checklist

What to include when requesting cancellation or return

• Order number and date of purchase or delivery.
• Copy of receipt or proof of payment (invoice, card statement).
• Photographs of sealed, unopened packaging or evidence of condition on delivery.
• Serial numbers, lot numbers or device IDs (if applicable).

Evidence for faulty or damaged goods

• Clear photos or video showing the fault or error codes.
• Dates and times of any app/device alerts related to the fault.
• Correspondence with Dexcom support, including ticket numbers or call logs.

Common mistakes

Missing cancellation windows

Failing to cancel a subscription at least 2 days before the next shipment often results in being charged for and receiving the next delivery.

Attempting to cancel an order after shipment without starting a return process can delay a refund request.

Returning ineligible items or using wrong channels

Sending back opened or used sensors typically voids change-of-mind refunds; products usually must be unopened and sealed to qualify.

Requesting app-store refunds through Dexcom instead of Apple or Google Play can cause delays; manage those through the respective app store.

Follow-up actions

Keep all cancellation confirmations, tracking numbers and communications until your refund or replacement is complete.

If your returned item is accepted, expect refunds within the timeframe stated by Dexcom (regional guidance: within 14 days of receipt).
