MTN SA appalling service

MTN Repairs center is unprofessional due to the fact that I sent my mobile device in from there Centurion Branch on the 15th of August 2019.Where I was told it would take 3 weeks for repairs.I had not heard a single thing about the phone until I called and sent the emails. I was then told that there was a back log. It is now 6 weeks later and nobody from MTN has the decency to call me and let me know what it is going on with my mobile device.Everytime you try and call the repair center number no one answers and everytime you request a number to call them they never send you a number just another email.No one even apologised for the poor service or explained what was going it is wrong to just ignore the customer especially when they are a paying for your services and this is how you treat them. When I went into the store to check on it the guy who was working there was not even helpful and he was rude. This is highly unacceptable and appalling service from MTN SA.
