HOW CAN WE HELP YOU!!!!!!!!! PLEASE CHANGE IT

I had debit order go of my account for R2300 odd, due to my credit card being in arrears, FNB did not notify me to say that debit order will go of, i have tried calling the debit order department and kept on hold to get cut of, i have emailed them and got a automated response, i have emailed again and got a blank response, i have said to please make arrangement, but no response, i explained to them that the money that they have debited is for my medical aid for my 2 kids that is 1 and 3 year old, i have as to please reverse that amount but nobody seems to help me, and the slogan says "HOW CAN WE HELP YOU".

FNB is useless and they do not help you when its urgent or priority, now my kids medical aid has been suspended and cannot take my 3 year old for treatment for his medical condition, i bet that FNB will never even bother to look at this or reverse my money
