*****ulent Debit Order

My account was *****ulently debited after I made my final payment and now I have to wait 4-6 weeks for a refund?? This is unacceptable. This is not a few hundred rand and I have other bills that need to be paid, where people are actually entitled to their money. I was forced to reverse the debit order through my bank and was charged a fee for this that they are not going to cover. Disgusting business practices from such a well known institution. NO other company takes 4-6 weeks to process a refund!
