Disgusting Service

I have three decoders with Multichoice. Multichoice disconnected my services on the 4th February due to non payment, I then called Multichoice to request them that I only need to reconnect only the Explora and also the extra view services and that they do not have to reconnect the other decoder since it is in the rural areas and is not being used. The agent gladly gave me the amount that I needed to pay for the reconnection of explora and the extra view, I then paid R495.00 and send the proof of payment as requested. The services were reconnected but today being the 8th of February the services were again disconnected citing the issue of short payment and that I’m owing them. My question was that since I’m paying in advance or pay per view how then do you say i owe you? My services are disconnected even though I have paid R495.00 was requested.

I really do not know how do deal with this matter.
