SuperSonic servicse

I regret signing up with Supersonic as a service provider. You can’t actually say “Service provider” as there is no service. No senior manager contact details is given and the consultants say they are not allowed to give out their information. You don’t get any feedback from consultants, but you are not allowed to phone any senior manager. I was quoted R645 for a 20meg line and got a 10meg line for the same price. I requested the voice recording and after months, they still can’t provide the recording or dont want to provide feedback. Surely if all the calls are recorded, it should not be a problem to recall the call and see who is in the wrong?
