Robbing Customers

I am very upset BY DSTV Customer service I phoned in by the 19th Sep to tell DSTV due to the liquidation of our company I would have to cancel my DSTV whereby the agent said she would get someone from the contracts department to phone me since it is a contract. I never heard anything from them except an SMS which said I owed them money and that was on the 29th October I then phoned in again and the same response was given to me that they would get the contracts department to phone me which never happened. I then received another SMS on the 13th Nov saying I owe them R527-56 I then phoned in again and the same response was given the contacts department would contact me as they could not cancel it since it was a contact. On the 30th of November, I received a call from the collection department saying I owed them R290-36 I told them I would only pay the R180 cancellation fee whereby I was told that I would be blacklisted. I then went onto the website and sent a message to DSTV via email, whereby a lady phoned me and said I needed to pay R470-36 I told her that DSTV is very wrong she then told me that nowhere on the system did it showed that I phoned in is this now the fault of mine that DSTV consultants did not do there work correctly, I gave a months notice and now they charge me R290-36 more than I was supposed to pay. I am disgusted with the service of DSTV after all these years that I was a customer to be treated this way I can guarantee you once I start working again I will never get DSTV and I will tell all friends, family, and anyone else I get to meet to cancel services via DSTV and they are dishonesty.
