MTN - USELESS!!!!!!!!!!!!!

I have had my new iPhone for almost two months now and still cannot use my contract correctly, had to go through porting my number from Telkom, and then moving over to nr for life, last week I had to call more than 5 times to get my phone working, I still cannot receive any calls on my phone its Easter weekend and the call centre is closed. i moved from cellc because they were useless, seems like I'm just sitting with the same issue again. it has been the most painful process to get a contract with MTN
