Unnecessary charges levied

I went to Diepkloof square branch to enquire about my account, when I opened a cheque account I was promised if I pay a fixed amount monthly I get free debit orders withdrawal and deposits, I also made sure there was enough money in my account for debit orders and now to my surprise my debit orders were not paid and now I owe the bank dishonour fees and worst of all a very rude consultant told me I have to pay the bank to downgrade. What happened to almost R250 rands I left for my debit orders. He told me I can't log a query unless I pay. What happened to customer satisfaction because I wasn't given any answers. FNB is a ******* bank and I will never bank b with them again. Ridiculous hidden charges.
