Mtn money hungry

I signed up a new contract with Mtn in Nov 2014. The debit order amount of which I signed for was R649. Since inception I have been debited R794 every month. I have been into the branch 5 times since and still nothing has been resolved. They guy from Bedford centre told me the issue was resolved in March, after I was debited R794 again in April I was furious. Went back into the branch for them to tell me they cannot help me as no one from the call centre was answering. What is the point of having these branches if they cannot even assist???<br> <br> Mtn are very quick to take money from clients but when it comes to refunding they can't seem to get it right.<br> <br> What shocking service I have received. I moved from another provider hoping that I would have a pleasant experience and each month it has gone from bad to worse.<br> <br> Over the past 3 months I have heard one too many complaints about Mtn and their accounts, seems to be a trend. Perhaps Carte Blanche could investigate???
