Terrible service and Knowledge from FNB

This the 3rd compliant i need to create, because nobody thus far can assist me, i have two debit orders that have been going off my account which i do not know about , I NEED IT STOPPED AND REVERSED, i have been contracted by the reversal department who cannot reverse it because according to them its not a debit order , then i was referred to ***** as it is a ********** transaction , when they check they tell me it is a debit order the manager of that department can reverse it . when i am put back to them they tell me its not a debit order, i`m then sent a form which i need to fill out , i tell the woman i did not make a purchase with my card for the thing to be reversed, she tells me i must fill out that form they will reverse it . i get an email yesterday after almost two weeks , telling me its a DEBIT ORDER THEY CANNOT PROCESS THE REQUEST, IT WAS NOT AT A MERCHANT. now i am asking nicely can sum1 who knows what they are doing deal with this query and reverse my debit order and all the fees in my account due to this inconvenience i have been dealing with . after looging this query i was asked to fill out a another reversal form which was sent to them 3 weeks ago still no response, in that time another 2 debit orders have gone off my account . so the debit keeps building but FNB cannot do a simple task by stopping these debit order.
