Sick and tired customer

I have been struggling to sort out my DSTV account. I made a payment on 7 December, then again on 20 December. My payment on 7 December is just missing, although it went of my bank account. I have send my proof of payment to ********** everytime. I get reference numbers and been told that they have send it to escalations to sort out. This is the last I here, until they switch of my DSTV and I send it again. I make calls to call centre, they charge me R50 for everytime they have to reconnect me. I don't even want to mention all the airtime I have to use. I only have a cellphone. I went to the bank on Saturday, sat there for 3 hours. I had them search for the payment that DSTV can't find for the 7th December. They say it went through to your account. I had them reverse the payment and made it again on Saturday(12/01). In fact, I paid R980. Then my mother in law call and say that there DSTV is of, that is paid up to date. So I call yet again and the lady(not very Helpful) say i must pay another R100. So I took my last money and pay the R100. This morning my main decoder on the premier package is switched off yet again Some of the people at the call center are so helpful and friendly, but sometimes you get those that just refuse to help. I am now sick and tired of this. I will send my proof of payment and my bank statement for the last time to dstv, thenIwill take this further. I am not a happy customer and will not stop with this until you have sorted this problem. The thing is, I have 2 decoders on my name and because I have a problem with a payment, that you can't find, both decoders are affected
