WORSE MTN REPAIR SERVICE

I bought 2 phones(P8 lite's 2016) on the 24 July 2017 and I returned my phone on 19 October 2017 because the display of the phone has a problem. now I called the repair centre and spoke to a consultant and she told me I must send in the proof of purchase. I asked why didn't they call to send it because now its been nearly a month now. I called today and the consultant said she need a box of a phone and proof of purchase or they will make me pay R2000 for the phone repair. I called again spoke to Tshepo and he said I must email the proof of purchase which I did and the system will be updated tomorrow. I hate being hustled around by MTN that's not a good idea because month end they will be excuses when deducting my account so please fix the company of yours. A customer doesn't have to make follow ups by himself were they should be calling us.
