DISGUSTED AND TOTALLY PEED OFF

I have sent numerous emails, telephone calls, and getting absolutely no response as to a debit order that is going off and they are not even dealing with the matter. They claim to be dealing with an MTN arrear account but MTN advises differently. The account is paid in full and now they will not respond as to where the money went that they took off on a debit order. We get responses to our emails about high volumes and will get back to us. Two weeks later and still no response.
