MTN NEVER RESPONDS TO QUERIES

So for the last 15 years I have had a contract with MTN. Up until recently this contract was under Nashua Mobile. Either way - MTN still providing the coverage etc Anyways - so my contract ALWAYS came up for renewal in Feb every 2 years. My brother and I had a contract that were taken out on the same day on the same account - and now all of a sudden MTN is saying that my contract only comes to an end on 6th June (whereas my brothers still comes to an end in Feb)???? MTN have FAILED to explain this in anyway - and have actually just failed altogether. I have tried SO MANY times to query this - but MTN's USELESS call centre do NOTHING but send another email to another useless employee who also just does nothing.<br> <br> I have asked how it was possible for me Contract to be extended without my approval? And also asked why mine was affected and not my brothers (that were on the exact same account) WHO APPROVED THE CONTRACT EXTENSION FOR 3MONTHS??? No one at MTN can answer this - and to make things even worse the USELESSNESS that is MTN says the last time according to their system, that my contract was renewed was in 2011 (FEB). So once again HOW THE HELL WAS THIS EXTENDED??<br> <br> PLEASE ANSWER ME
