MTN service sucks

I have been a loyal MTN customer for almost 20 years and the service seems to be getting worse and worse.

I regretfully did an upgrade at the beginning of September and my contract came with a "free" memory card. Not only have I not received the memory card, which I have actually paid for, I have gone into the store 3 times, called them over 50 times (and only managed to get through twice) left messages that have never been returned, and sent someone else in to find out what is going on for me. I have been told that the person I need to speak to is unavailable, then they are on leave, then the consultant is on leave, now MTN has no memory cards. How can a company that provides cell phones and services have no memory cards for weeks on end?

The last time i upgraded over 2 years ago, my voicemail notifications stopped working and i have logged over 20 calls in that regard. In 3 years noone has managed to fix my voicemail issue, no matter who i speak to or how many times i ask.

MTN your service seriously sucks.
