MTN Unfair billing

MTN has debit my account for March for the full amount but the handover from Autopage to MTN only took place on the 17th. Whereby autopage has debited my account for up to the 16th of March already.<br> <br> Ref from MTN, Call Ref, 158....., 160....., 161..... SMS ref 1-178... - I was advised the query will take 48hrs.<br> <br> I have now called again 15.04.16: Ref 1627......, the call agent advised me that she can see on the system supporting docs are needed if a refund is required.<br> <br> My question,what docs are required? No one has called me, nor mailed me - nothing?<br> <br> Why must I call 100 time with no positive response or feedback, they debited my account and I feel that this should have been sorted out between Autopage and MTN and not affect me as the consumer.<br> <br> Jenna
