Payment not deducted and no response from MTN

You guys have not been deducting my payment for a laptop I took out on contract. Last time I spoke to your consultants, they asked me to make the payment manually as my account was now with legal department. I made the payment immediately and asked to put my account back on direct debit. This has not been done even if I have already provided you with my account details!<br> <br> You guys are not responding to my emails and getting hold of anyone at your call centre is near impossible since I am put on hold for hours!! <br> <br> Because of you people my credit rating is taking a blow! How do I make the payment for last month and this month? I do not want to make the payment manually again and then the direct debit goes off this month and I do not have enough funds on my account or I end up paying twice for the month!<br> <br>
