Telkom mobile's payment method is a ****

I have been trying for the last 5 years to get telkom to remove a debit order from my bank account. I even went to my bank to stop the debit orders myself. Telkom continuously adds extra fees to my mobile bill AFTER I told numerous agents that I pay my bill via EFT monthly due to my bank account having been hacked 3 years ago. Telkom refuses to help me or to assist, when in their T's and C's they mention 'cash payments' which had been explained to me as EFT payments or ATM payments. I even pay more on my bill that what I am initially charged for. I have now - again, after how many times - been handed over to NuDebt Trust. I am sick and tired of this treatment from a so-called fantastic mobile company. I pay EFT monthly, had even informed the agents of this, but they are being unhelpful. But Telkom is quick to phone to offer new deals and better monthly instalments on routers and new phones. Telkom mobile is a **** when it comes to their own T's and C's
