*****ing money from my bank account.

I want to warn the public about signing a contract with MTN.<br> In March 2015 I signed a contract with MTN and my SIM was activated.<br> To my surprise, a few days later I got an invoice from MTN to the amount of R12.41 for part of the month of February.<br> MTN was also very quick to deduct that amount from my bank account. <br> I went back to the MTN shop where I sign the contract, they gave me an official signed letter, confirming that during the Month of February I had no service what so ever, and advice me to contact MTN customer care.<br> I sent them the complain and I got a request number in return. I didn't hear from them again.<br> I went personally to MTN customer care center and the consultant promised to sort it and to inform me when it's fixed. I heard nothing after that and I got no refund. <br>
