Frustrated, annoyed and disgusted

I recently took my damaged phone to the HVRC in Midrand. I had to call numerous times to check the status and eventually I went to collect my phone. The lady that I dealt with asked why I didn't request a new phone as it was still under warranty. According to the CPA, I am within my rights to request a new phone, but this wasn't communicated with me at the time I booked my phone in. If there is a legitimate defect with my phone, then I would prefer a brand new one instead of a refurbed phone that I now have. That still isn't where this ends... The lady at the centre checked my phone and all looked to be in working order. I returned home only to find that my phone was missing the sim tray, rendering it absolutely useless! I immediately called the *** number to report it, and was told that I would have to call back the next day to follow up. This happened three days in a row. In total, I have spent 83 minutes on the phone to MTN customer service only to find that I am being charged for these calls! It has been over a week now, and I am still waiting for someone to contact me with a solution. The service received has been pathetic and MTN should be ashamed of themselves!!!!!
