Frustrating Telkom Service

Debit orders going off on dates no authorized. Debit order went off end of May, account suspended due to non payment. Agents at service desk not helpful. Very disrespectful and insulting. Sent various emails and no feedback. I have to cover the costs of these debit orders and Telkom is really making me sick. Everytime I've got to fight with them and they can't give me feedback. The debit order went off but they can't find it. How's it possible if my bank statement shows a debit order for telkom but they never received it. Where is it then? Telkom tells me, contact your bank and look at your statement again. I'm furious because they don't call back, they don't reply to emails, they quick to run debit orders but they can't help a customer. Agent says to me, the collections department sniffs accounts. This is beyond upsetting and frustrating. No one calls you to advise, no, they just hand you over.. there is supposed to be an investigation regarding where my debit order has gone to but no.... it's my fault it went off and it's not showing.... this happens so often.....
