Supersonic WORST ISP IN SA

After our wifi went out THURSDAY 18/11/2021 we spent nearly R2000 on airtime on the phone with the consultants who none of which assisted us AT ALL !!!! Needless to say our wifi is still off!! We have tried to cancel our line and we sent the email to the cancellations at supersonic email address, but have still not received our cancellation letter that we need to switch to our new ISP , we phoned again and when asked they told us to send an email to the same cancellations email address, we got an automated response that said this was an unmanned email inbox and we must phone, we phoned again and the consultant simply told us to send the email to the same address again! We need assistance desperately and no one is willing to help us, FOR A SERVICE THAT WE HAVE PAID FOR!
