upgraded by somneone else

Two years ago a guy upgraded my contract instead of migrate it to his account by a lady in Johannesburg.<br> This happened because the lady was to stuppid to do this without taking in account to the rules needed to do the migration, three months bankstates, copy ID etc..... so end of story Im debited for the last two years for that contract. the lady in the shop doesnt want to change a thing as her manager in the shop. and after a lot of phoning and emails I received a mail from MTN that they would refund and change the contract to its old standards which was better than fockhol, so ok. But that is again 4 months ago and nothing has changed, they still debit my account in full. I can cancle the contract from tomorrow, which I will do, together with all the other numbers I have there, and see what a attorney can do about this, since the amount debeted now is worth enough to pay the attorney:) Richard
