Supersonic is a South African internet service provider offering uncapped fibre, 5G and AirFibre packages. The company is powered by MTN with claimed 96% coverage and partnerships with fibre networks including Openserve. Plans range from 10Mbps to 1Gbps, with promotional pricing starting as low as R139–R299 per month on month-to-month contracts. Supersonic promotes “lightning-fast” and reliable internet for streaming, gaming and remote work. It provides a formal complaints process via email, with escalation available to the Independent Communications Authority of South Africa (ICASA).
However, independent customer review platforms show consistently poor performance. On HelloPeter, Supersonic holds a 1.6 TrustIndex rating based on 739 reviews in the last 12 months, with 95% of those reviews being 1-star and an NPS score of -96. A related SPF page shows a 2.1 TrustIndex with 100% 1-star ratings in its recent reviews.
On Trustpilot, the company is rated 1.3 out of 5 stars from 362 reviews, with the summary noting widespread dissatisfaction over connectivity outages, unresponsive customer service, billing discrepancies, installation delays and refund difficulties. The company has not replied to negative reviews on these platforms.
Recent HelloPeter reviews (March 2026) include:
- Customers reporting no internet connection after installation, unreachable call centres and WhatsApp, plus unexpected “clawback” fees and cancellation problems.
- Overcharging during promotions, threats of legal handover for disputed amounts, and automated responses with no human resolution.
- Billing errors such as double-charging after switches or continued debits despite proof of payment.
Trustpilot reviews from February–March 2026 describe similar patterns: prolonged outages (e.g. days without service), ignored support tickets marked “resolved” without fixes, unauthorised activations, delayed refunds, and speeds far below advertised (sometimes as low as 10Mbps). Installation delays exceeding one month and difficulties cancelling services are repeatedly mentioned across platforms.
Forums such as MyBroadband have documented ongoing issues since at least 2023, including a February 2025 report noting multiple complaints about service levels and a flooded HelloPeter page. Users on X (formerly Twitter) in 2024–2025 have posted about installation delays after MTN orders, service suspensions despite payments, and poor streaming performance due to provider policies.
Positive feedback is extremely rare in recent public reviews. While the underlying MTN-powered network is occasionally described as capable when active, the dominant issues centre on customer service inaccessibility, billing inaccuracies (including bounced debit orders without resolution and arrears despite payments), and failure to activate or maintain promised service.
These are factual reports aggregated from verified customer platforms as of March 2026. Supersonic remains an operational provider with no reported closure or regulatory shutdown. Affected customers can follow the company’s complaints procedure or escalate directly to ICASA.
PrimeTime News ZA advises consumers to check coverage, read recent independent reviews on HelloPeter and Trustpilot, and document all payments and communications before signing up. If you have experienced similar issues with Supersonic Fibre, consider logging a formal complaint with the provider and ICASA for official resolution.
