Bad Service

My phone was suspended due to non payments and the account was handed over to the attorneys. I paid the outstanding balance on the 30th July 2015 from then I have been trying to get mtn to update their records accordingly and release my number, still no success. I 1st went to the store in Zavenwacht mall after I paid, they faxed the proof of payment to the Head Office and advised me that the system will be updated after 21 working days. After 2 months I went back and spoke to someone else who advised me differently, saying that the account is still with the attorneys, I should be calling the attorneys directly there is nothing they can do on their side. I then called the attorneys who also advised me that the account is no longer with them I must call mtn. I called mtn head offices again they gave me their legal department's number which is ***. I tried calling that number on a number of accasiond and nobody picks up. I called the mtn head office to advised them of the same. The lady I spoke to advised me to keep calling they might pick up, she has received similar complaints. Todate I have not been able to get through. I am really frustrated with mtn!!!!
