Can't allocate my payments

Multichoice keeps on disconnecting my DSTV and I keep on sending them the proof of payments. I have phoned them like 5 times already in one month and everytime they give me another e-mail address to send the proof of payments to and everytime they tell me they will sort it out. This is very bad and poor service and it is like *****ing, you pay for something but you don't get the service and I must phone them and all my airtime is finished everytime I am done speaking to them and they are not crediting me for my airtime. Can you please assist me with this and I am using the correct account number which they gave me. I make EFT payments for the last 6 months now but why is only July and August a problem all of a sudden??? Who is going to be pay the reconnection fees??? I did pay but nobody is doing anything about it, they jus disconnect my DSTV. We need your help Peter so that Multichoice can start doing what they are paid for stop wasting our time and money as this is getting very frustrating and irritating.
