MTN ***** ACCOUNT

an MTN account was opened last year in my name, so i went to the MTN store in gateway to report this matter, they told me i need to submit and affidavid stating that i did not take a contract with them, i did all that, went back they submitted to their ***** department, twoo weeks later i went back to the store, they confimed it has been closed, they even confirmed this when they messaged me on facebook, but when i requeste for a letter proving this, they keep sending me around, to call this number and that number, there is no answer on their *****'s line ********** 466. in FEB this year i revived a call from SSD, i have been handed over, they told me the only way for them to stop calling and smsing is if a send a letter from MTN saying that the account has been canceled, so i went back to their FB because those are the only people that actually respond, i told them i need a letter and asked how is it possible that i have been handed over after i was told that the account has been closed? till now i am still waiting for feed back. MTN's service is horrible, its even more frustrating when you cant get assistance, each and every person i speak to tells me straight that they cant help me, i need to speak to their ***** department, the very same department i cant get a hold off, the phone rings non stop like its home affairs. i need some assistance, i can not be black listed for something i did not do.
