Cancellation service #1 in South Africa
Sonic is an internet service provider operating in South Africa that offers fibre and wireless internet plans. It positions itself as a provider of high-speed, uncapped fibre and capped wireless plans.
Services include uncapped fibre packages at multiple speed tiers and capped wireless data plans for lower-cost or mobile-style usage. Installation may require provider-supplied equipment for certain wireless connections.
Your service generally remains active during the one-month notice period and will typically terminate at the end of the next billing cycle. Expect final billing to reflect the notice period.
Provider may request return of supplied equipment, charge for damaged or unreturned equipment, or recoup the value of promotional discounts if contract terms allow.
Under South African law (ECTA), consumers may cancel a service agreement within seven (7) days of signing for any reason.
If you exercise this right, you must receive a full refund within 30 days of cancellation under the cooling-off provision.

ECTA provides a seven (7) day cooling-off right for services: you can cancel within 7 days of signing and must receive a full refund within 30 days when this right is exercised.
Under the telecommunications Code of Conduct consumers have rights such as non-discrimination, access to account records, the right to lodge complaints and seek redress, and protection of personal data.
Some customers report good outcomes where individual agents took ownership and resolved issues effectively. Positive experiences often cite helpful, responsive support when escalation works.
Many complaints reference unreliable connectivity, slow or ineffective customer support, billing disputes, unexpected charges, and difficulties finalising cancellations or receiving confirmations.
Not providing a written/email cancellation, or failing to give the required one-month notice, is a common cause of continued billing after you intend to stop service.
Assuming cancellation is complete without obtaining written confirmation can lead to unexpected charges. Also, not returning provider equipment or not documenting its condition may cause fees.
| Platform | Notice required | Refunds | Equipment charges | Notes |
|---|---|---|---|---|
| Supersonic South Africa (general) | One calendar month's written/email notice | No general refunds stated; liability may be capped at one month | May recoup promotional value and cost of supplied/damaged equipment | Provider reserves rights to reclaim promotional subsidies |
| Sonic South Africa (fixed wireless) | One month's notice via email to billing | Refunds limited; check contract and ECTA cooling-off | Under-contract hardware may require buyout or arranged removal | Fixed wireless may involve on-site antenna removal conditions |
| Sonic (international ISP context) | Typically 30-day notice via portal or phone | No refunds on prepaid services; cancellation effective next billing cycle | Equipment return or charges depend on local terms | Check your local service terms for exact requirements |
Use the table to verify which rules apply to your account before you cancel. Always confirm the notice period and equipment terms that are specific to your contract.
