No AFTER SALES SERVICE

I am truly outraged about the level of serves MTN gives there clients. My MTN account was in arrears last year due to some difficulties . But this year in Feburary I paid my account in full. I have the proof of payment from my bank to back me up. I struggled for weeks to get a paid up letter from MTN `S legal dept and only received it in April of this year. I decided to leave it there. A month ago I app**** for a home loan but was declined by several banks , when I asked why I was being declidened I was told that MTN wrote off an account in my name and that I had to pay this account in full. I then contacted MTN about this and I was told the account was paid off but I had to contact ITC myself to get it removed from my name . That I find truly unfair because why was I not informed about this in Feb but I contacted VCCB in regards to this provided them with every thing and a dispute was logged. On Monday I phoned VCCB to find out how far they are in regard to my dispute. I was informed that MTN has not rep**** to there emails. I then phoned MTN to find out what the problem is I got transferred to several department each one stating that it was not there fault I should hold for the next person. I finally got to legal and was told that they cant do anything about it and I got transfers to a debtor this lady was absolutely rude to me screaming on me that its not her problem and that she is not going to help me I should contact MDB . I contacted MDB the guy there assisted me and told me that mt file was no longer with them and it was handed over to MTN , I explained the situation to home, and he stated that the Legal dept at MTN is the only dept that can help me. At this point I am very mad but thank home for his help. I phone MTN again this time another lady helps me stating that I wont get help from MTN if I phone or email and I have to go to the walk in center in Roodepoort to get help , I live in Vanderbijlaprk there is no way I am driving all the way there just to get this sorted out . I am really upset about this all I want is for MTN to remove the account from my name so VCCB can clear my an,e and I can get a homeloan .
