Services not working

I had a problem with my DSTV XTRA View connection, called the call center and never found any joy. Then I sent an email with my connection with attached with the reference number I was assisted. However a week later my secondary decoder started playing channel 100 only and a day later the primary decoder did the same thing. I spent the whole weekend with channel 100, the consultant was able to fix it but after an hour still I don't have channels. The error Msg was that my account is in arrears, however my next payment is by the 28th of September 2015. I paid for my services and I am not getting the route cause to this issues. If it was me who missed a payment by a day, my services will be disconnected and I have to pay a penalty. But now I don't have services and I paid and there is no one to assist efficiently with this matter. I cant pay for unhelpful calls made to the call center and pay for services (no matter what price) I should get proper assistance. All I want is assistance.
