Bad service and protecting their ageny

My name is Ali I filed a complain about the Dstv, whereby they say this and do that. I paid for my dstv on the 25 June and we argued and argued until they fixed it. Now all of a sudden yesterday the switched it off, what they are doi g is that they protect their agent that told me that I will pay on the 7th August as I have upgraded my package and paid the amount she mentioned. When they play the recording they cut it where the agent was stating that on the 7th August. They always say our calls are recorded but when you ask them they say the agent didn't call me whereas the call was cut then they called me back, but when they check their system doesn't show that the agent returned the call. That's is what Andile said the other agent. I'm not happy at all about your service Lobisa Fumba and d your crew stop this thing of making us puppets. We pay for our services so now my kids have to suffer because of the negligence of your agent. I will not pay on the 23rd July and pay again on the 7th August. Exactly what's going on with DSTV lately. They need to tell me what to do now cos I won't pay 2 payments in a space of days.
