Incorrect deductions

Good Day<br> <br> This is my second complaint within less than a year about MTN. I am experiencing the same problem where ******* deductions are being made from my account. <br> <br> I have addressed my concern with MTN on 8 March 2016 but to date have not received any response. This is becoming very, very annoying. i cannot keep monitoring what MTN does on my account. In addition to this, they promised to refund me the extra deductions made but to date i have not been reimbursed.<br> <br> Please, please assist urgently.
