Worst ISP in the country

If I could rate Supersonic a 0 star, I would. Their level of incompetence is astonishing. They have no idea what they’re doing, routinely gaslight customers with valid concerns, close support tickets without resolving issues, and ignore all customer communications via telephone, email, and their ticketing system.

I have used several ISPs here in South Africa, and nothing compares to the stress and inconvenience Supersonic has caused me. Their internal mishandling of customer information has even led to accounts being sent to collections ********ly. I find it unbelievable that a company with over 400 one-star reviews is allowed to operate without any apparent consequence.

This is, without doubt, the worst and most inconvenient ISP I have ever encountered. Their customer service is practically nonexistent. The billing department arbitrarily charges incorrect amounts—even unauthorized ones—and never takes accountability. When you call, you’re left on hold for minutes or even hours with no resolution in sight. Management fails to escalate issues when requested, and when they do respond after a long delay, it is with generic, unhelpful answers that never address the concerns of paying customers.

In summary, Supersonic’s overall performance and service delivery are utterly unacceptable.
