Paying for something I can not use

I have moved over to price lock in May of this year. Since then they could not get my other account cancelled so still get billed for it. I was told I owe them money every time I phone to find out how much I need to pay I get an amount I pay that and then I got told I am in arrears. I have a constant fight with them to keep me connected as if I have it on Debit order they take off way to much then it bounces. So no I have resorted on paying it via EFT and transferring it to the correct account. Since May this year I have phoned them every month asking to be reconnected and getting a story that I am in arrears. Then I ask for a statement to prove that I am and I get nothing. I then downloaded the statements from their internet service and did my own recon on the account and then it came to they owing me money as I was being over charged. This all done in September. The only month I was not disconnected was October where I did not have to call them to get reconnected or anything like that. I have spent over R600.00 on airtime over the year just on DSTV to get this sorted and yet no results. I still owe them money. Asked for a recon of my account from them and nothing. I am so sick and tired of DSTV. I see now why people just get WIFI and do the Showmax and Nettflix story. Hope to hear from them soon.
