Debit order

Telkom mobile has truly become my worst nightmare, after my query with the spend limit that was loaded onto my account without my knowledge. I made the payment which was double my monthly subscription and was advised that the normal amount would be debited end of March. I was debited before my payment date I queried it and was told it was an error and would be rectified end of March. My debut order didn't go off end off March I queried and was told it would go off on the 1st of April, it didn't go off I query it today and am told I again must go make the payment manually. This is completely unacceptable how Telkom has been handling my query. This is by far the worst service provider I have come across and the call cntr agent and managers don't even care.
