MTN *** NOT A*** still not resolved

This will be my 4th complaint about the same complaint. :-( On the 04/02/2016 I received feedback from MTN- that I must fax all my documents and correspondence to *** with ***. I did so immediately. Today is the 11/02/2016 - and still nobody has had the decency of calling me. Might I add that this query has been going on since December 2015. I want a statement of acc A***, not A***. MTN cannot give this to me, as you have deleted the account and migrated it to a pre-paid number. I've been paying my account off and was only told in Nov 2015 to stop paying - only because I asked for a settlement balance. When was this account migrated into pre-paid. Why did they not advise me sooner, why only when I asked for a settlement balance? I am 100% sure I paid money and it has been allocated to someone else's account. I want my money back. I don't care about the cell number. I don't even use MTN anymore due to the lack of assistance and professionalism. I am thinking of taking this matter to small claims court or legal aid. Maybe then, I will get my money back.
