NO response or reply

I got an sms from Cell c stating that my debit order failed and my service will be cut, to make arrangements i need to call 084140, So to make arrangements i call their "Customer Care", when i spoke to an agent they said they will log my querry and their accounts department will call me within 2 days , This was wednesday 08 november, On monday 13 november I called again having no response from cell c exept the same sms coming through. The Agent this time told me the previous agent made a note but there was no case opened. So he opened the case for me, and gave me a reference number and once again they will contact me in two Days. It is now Thursday 16 Nov, and still I have no feedback. This is utterly unacceptable service. I am cancelling my Cell c contract and going to a service provider that will actually respond to their clients.
