NO RESPONSE FROM ACCOUNTS

I have had an accounts issue with MTN since January 2015, which has STILL not been resolved although I have phoned, written and been into MTN office on several occasions. This is the problem:<br> <br> 1. I had a contract in place (R199 per month) on cell numb ***<br> 2. The contract was due for an upgrade in January 2015.<br> 3. We upgraded for a Samsung phone. the courier delivered the wrong phone. I returned the phone immediately with the courier. We never received the correct phone.<br> 4. After waiting over a week for the issue to be resolved. I cancelled the upgrade.<br> 5. The upgrade fee was eventually reversed.<br> 6. However, I have been billed every single month the \upgrade monthly amount"of R278 - instead of the R199 as was my original contract.<br> 7."
