MTN illogical policy and bad service

My daughter has a contract with MTN. Her phone, which was still under warranty, started playing up in that she could not hear the caller. Sent to MTN who took it for a month. Then quoted R8000 to fix, before they could review the problem. In other words they said there was some damage which they would have to look at and when in perfect condition, other than the speaker problem, could they look at the speaker. We took the phone to Wefix who had it for 2 days and fixed the problem for R799. The MTN Steenburg store were very unhelpful as was MTN. So it’s simple, as a family with 5 children all of whom have cell phones, we will vote with our feet and leave them as and when the contracts expire. I have been an MTN customer for around 25 years and must be their longest or close to their longest customer, having kept my number all this time. But I cannot stand back and let the terrible service to my daughter, which would have resulted in a large cost to her as a student completing her final year of a CA Degree, keep me with MTN.
