No account and no contract??????

MTN just advised me for the third time that I do not have a contract with them. Nor is my details on system. This after I upgraded a year ago with MTN just after they took over Nashua Mobile. I had a cintract for 10 years no problems..untill now.<br> My contract was a R300 contract. They debited R2700?!!!<br> I had this reversed. I contacted twice and went to a MTN shop...nothing. no profile no contract nothing. I am still receiving my monthly airtime and just got an email saying I have reached my limmit? The lady at the call centre adviced that there is nothing on system. I requested a letter from MTN confirming this as I am not going to be held liable for any ammounts owing after confirming three times that I do not have an account. I am done with MTN<br> I will most likely not even receive my letter and will have to go to a shop again on ky own time <br> WONDER IF I WILL GET FEEDBACK ON THE ABOVE
