I wrote on Hello Peter on the 1st of February 2019 about my phone which MTN Paarl cracked the screen and kept me accountable. the phone was handed in on 8 Jan 2019.still this matter is unresolved and while my phone is still under guarantee. MTN please man up , I still pay my contract, and this while I do not have a phone. I have all the forms that my phone did not had a cracked screen when handed in. MTN please solve this problem, it is already a month went by.
