Telkom Mobile debit order saga

If I could give a negative score I would for Telkom mobile. I am wondering if I should continue paying for services that I am not enjoying. This is the second month where after a few days of making a payment my line is soft locked. At some point I owed Telkom money which I gladly paid. I have asked twice that I want to make an EFT payment and Telkom should not debit my account and twice after making a payment they collections department ran a debit order. Twice I have had to reverse the debit order because I have already made the payments. Their statements will show that payments had been made. The reversal of those debit orders are costing me money and Telkom is charging me extra for money that they have recieved and this is where the dispute lies. I have requested themseveral time not to debit my account which they did and I have had to resort to closing the account because I am told their "system" cannot be reversed which I believe is nonsense. I have communicated to them that I have closed the account because I cannot be debited for an amount that I have already paid. Telkom despite having spoken to numerous consultants they continue telling me that they are debiting the account. I have been paying the contractual amount on the 25th ofevery month for two months now and my line will be opened just for a few days and closed for the rest of the month. Should I continue paying for services that I am not getting? The extra amount which they say I owe is as a result of them debiting my account after they amount has been paid via EFT. I do have a case number which they closed without resolving it. Should I continue paying for services I am not getting? Absolutely not. I want them to reverse the debit charges that were made ********ly. This is going to be the 3rd month where I pay with no services rendered. My phone currently locked and yet I have paid the monthly subscription. The case number that I was given is ***7. I am getting tired of paying for services I am not getting. I will not be paying the contracted amount moving forward as I am not using their services despite my paying the contractual amount.
