Supersonic Internet provider don't allow cancellations.

I canceled the service or at least attempted to cancel as Supersonic doesn't have the upgrade package I require. The outcome was that Supersonic is like a jealous EX refusing to let you leave, as cancellations are not acknowledged and the line is not released but kept hostage until they forced you to return to them. It is impossible to get through to their contact center as I have been trying for the last two weeks and bought on average R40 air time just to be on hold for 15 mins and eventually not being able to speak to a consultant as my airtime was depleted.I changed my strategy and selected the option of wanting to sign on as a customer and not even, 1 min on hold and I spoke to a consultant, who just transferred me to the correct department and the same outcome as my previous experiences. Customer service is not part of their business strategy as it is not important as they don't allow you to leave. *** Henry Maans.
