Disgusting service

Good day

I am being penalized now with a clawback charge. Because the upgrade department did a payment jab on my account twice knowing that I don't have the funds in my account. And then they changed my debit order date as well. Now since the debit order didn't go through they want to charge me a clawback fee. I have disputed this issue and my service has been suspended in the meantime but I have been advised that since the complaint has been escalated that this would not happen. I even received a mail stating that my services would be restored within 24hrs but still nothing. I am really unhappy with this service and I am willing to pay an amount due. But the fee of R6300 is an error on their side Called and called and sent mails but no one assist me. Just straight tell me that I must pay
