Account suspended after being debited

Hi Telkom. Could you please urgently re-instate my services on my mobile account. You debited me for an amount of R875.06 on the 16/03/2016. I received an sms from you on the 18/03/2016 that my account was suspended and I need to call the call centre. I have called a few times, only to be dealt with call center agents with bad attitudes. My query remains unresolved. I don't think its fair to take my money and still suspend my account. I was not even supposed to be debited on the 16/03/2016 in the first place. I do not owe Telkom money. In fact Telkom owed me money and I was in a credit balance with Telkom, but somehow my credits were not reflected on my latest bill, sent to me in the beginning of March 2016 and as a result Telkom billed me incorrectly. Please sort this out asap. It shouldn't even take you 5 mins to update your system with the correct information.<br>
