Pathetic Customer Service

Cancelled contract last year Sept after the contract has expired, because of the pathetic service. Still billing me, and had the audacity to HAND me OVER! Numerous e-mails to customer service, cancellations and retention dept's. Reference numbers for all mails. NO FEEDBACK. 21/05 I was on the phone with retention dept, spoke to Ayanda, for 58 minutes! Eventually she told me that the supervisor, Faruk, would phone during the day, which was 21/05, I gave her my cell number and 2 of my office numbers. Up to now, 22/05 18.10 I have not received a call from this so-called supervisor. My HUSBAND received a call today from MTN, he gave them my cell and 1 office number, and yet I have received no call. This pathetic service is confirmed by the MTN branch in town, telling me that they are also sick and tired of head office who cannot sort out any customer problems! How pathetic is that! MTN's own staff cannot rely on back up from their own head office AND THE BRANCH STAFF HAVE TO FACE THE CUSTOMERS!!!!!
