Query Remains Unanswered.

On 10 Feb I sent an e-mail with some queries re my account. The next day my e-mail was forwarded by Mpho Mashigo to Mpho's 'Team' with request to assist. 2 weeks later, having received no response from MTN I sent another e-mail asking for a response. I have now received a reply from Ntasang Mocheku advising that my query has been escalated to the relevant department. No reference as to what department it had been escalated. I was also advised I could contact the 'department' on 135. I did call 135, and after some time they said they would put me through to the credit controller. I was then supposedly put through to them. After some 20 minutes holding on, waiting, waiting, waiting, my patience ran out and I ended the call. So, still no answers to my query. This call centre is pretty useless!
