DSTV agrees to making error but can't pay money

R1729.00 was deducted from my account by Multichoice today when my monthly installment is R799.00. After contacting them,they agreed that it was an error on their side,but can't give any feedback of when or IF my money will be reversed and the problem will be solved. This is the most pathetic service I have ever encountered in my life and I am willing to take Multichoice to the media for THEFT! Someone please contact me if you can find out what's going on because MULTICHOICE can't even tell me when what will happen. I am DISGUSTED with the poor service and the call centre is useless! What does it help to contact a call centre if they can't solve problems but they can tell you that it's an error on their side.
