PMT HONFEE - Double Debit

I am absolutely devastated by the service i have received this passed week. <br> <br> I called on Monday, 04/01/2016 to put a debit order, delete my card from my account and set a fixed amount to be deducted off my account for my credit card every month. After already paying for January, Wednesday, 06/01/2016, they deducted the fixed amount again from my account causing me to go into a minus. I called yesterday after being on the phone for half an hour with a lady who kept telling me she is sorry for the inconvenience but i have to wait 5 to 7 working days before i get it back due to the fact it was a system error. After explaining that i now have NO money as im in a minus as they could see, she told me there was nothing else she could do but try get it in 3 to 5 working days! I then see that FNB has deducted R50 for a PMT HONFEE!!!! This was not my fault and i tried my best to get money back in my account as this was FNB's fault yet i still get charged for their mistake?
