"Don't do business with them"

Don't do business with them. Have been trying to speak to someone for 2 weeks now. WhatsApp not working. Call centre cuts off call after more than 20 minutes hold. And messenger is even more useless.

"What a waste "

What a waste , I was called by an MTN agent to assist in getting the fiber on the 9th of January which was a package for R559pm I don't know how or where they got the R1299pm package however that's what I was given, I have called , emailed lodged multiple tickets even made contact with MTN and still no one can get the call recording of the correct package I ordered this is the worst experience ever as I write this I've been on hold for 30 minutes and I'm not hanging up until I get the consultant next thing they will try to hand me over to the lawyers just because I refuse to pay for something I did not ask I wonder why is this company still operating this is day light robery and we as their customers are never gonna be protected I am canceling my subscription

"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 unlawfully. 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.

"Worst service ever"

Worst service ever. I pay for a 100 Mbps upload and download line but it acceptable for them to get average 20 to 40 Mbps. Tried laying a complaint and was on hold for 47 minutes with no answer. I decided to move to another isp and terminated via the portal. The termination department contracted me once and sent a sms that they could not reach me and I need to request a call back via Whatsapp. Sent request but it does not get answered and after a while gets closed.

"Worst service ever the fibre has no…"

Worst service ever the fibre has no internet connection all the time no one answers phone calls no service you pay for nothing I'm stuck wth fibre wth no internet

"This Co is a joke it has no proper…"

This Co is a joke it has no proper communication or what soever, the internet just goes off anytime it's wants when I contact support on what's up, what's up is under maintenance soon as it runs out of data I'm canceling it I'm tired of reseting and unplugging it does not work.

"Bad call center service"

Super sonic customer care call center nobody answer your call I had to wait for 50 munits holding on and listen to the computer answer machine

"STAY FAR AWAY FROM SUPERSONIC THEY A SCAM"

Absolutely useless, we have no internet fibre connection since December. The refuse to send out a technician. All they do is ask you to unplug and reset the router which doe's nothing. Those technicians avoid work at every chance. So I cancelled the account today.

"Supersonic super pathetic. "

Bought a data package via Supersonic. Router needs to be reset continuously despite good signal. Not supported after 20h00. Operators cannot fix the problem other than through a re-set. They are rude and simply cut you off after you have held for an excess of 30 min.

"Absolutely no communication"

Absolutely no communication. Placed order and payment before Christmas 2024. No router delivered and after countless attempts to contact them, still answer. Tried Facebook messenger, Twitter, phone calls and emails. Nothing. Trying to get out of this contract and get my refund. Also nothing happening when you log in to their website.
