Disgusted

I am totally disgussed with mtn service at the glen shopping mall and the repair centre. My phone crashed and I took the device in for repairs at mtn the glen, sloppy service first of all, told the lady my phone has a small crack at the back and under no circumstance do I want them to replace that because i brought the phone in for software problem. A week later I called the service centre, pathetic service, no one could assist me. Today I get a sms stating I need to pay R656.7 for the cracked screen at the back or R330 if I reject the quote , disgusting way ofdoing business and trying to milk people out of their hard earned cash. I am totally disgussed!!! I will not pay this you are forcing me to pay u money regardless. I was not made aware of this. Keep ur phone and cancel my contract !!!
