MTN IT system a joke

Do not upgrade with MTN. I upgraded, received my new invoice and confirmation of upgrade, but none of my 250 minutes as per my new contract were allocated. I now have to buy airtime, since it is the 16th of the month and I still have not received a single voice minute!! I have logged 2 queries already, but somehow MTN still cannot fix this? The lady helping me was great, but MTN's IT system just cannot cope with fixing my issue...surely this cannot be such a complicated problem to fix!
