Bad service from supersonic MTN

Unfortunately I am very unimpressed with the service I have received from supersonic with regards to cancelling my WiFi contract. I have been waiting almost a month for them to respond to me with regards to the cancellation. They have not made any effort to contact me and quite frankly I find that very unprofessional. I contacted supersonic with regards to canceling my contract at the end of January and I have still not received a response. Supersonic will than want to charge me when I informed them before the month even started. We are now approaching the end of February and still nothing. I am very disappointed in the service and I would not recommend connecting with them.
