Bad service

I am a dstv customer.I paid my monthly subscription on the 28th of February. My service was disconnected on the 9th of March. When I called to find out about it they asked for the proof of payment of which I sent immediately. I then got a call saying they can't find the payment on the system and I had to go straight to MultiChoice and the consultant there said there was mix up apparently my service was changed from compact to compact plus that's why it got disconnected and promised to reverse it and reconnect but till now that hasn't happened. When are they reconnecting. Why are they changing my services without informing me first.
