FNB How can we Help (ourselfes)

I have stop a stop order 2 years back several times. In the bank as well as over the phone.... I stop all debit orders up to the amount of R5000-00 It was confirmed that stop orders was stop, but yet again and again moneys was debited and there was no funds in account. so now the bank add cost on my Cheque account and I opened a new account at another bank. I ignore FNB as they cost me moneys. Last month a person paid in moneys wrongfully in that account and contact me R2000 was paid in. I contacted the bank with no success. then i found that my account is still active but I am in arrears and debt of over R5000.00 i was in the bank as several calls cost me more than R50 in calls and i must wait. I explain myself over and over from one department to another. No success. I finally went to my Branch and even there the woman tried to help by calling departments in the bank. still no answer and she explained herself 4 times. at last she did a mail on request of a director of the division but 14 days past still no answer. Two days ago I sent a mail myself to complaints and just a confirmation of complaint received was sent to me. REF Nr of complaint *** FNB make it impossible to complain or get a request done. They want your monies and ***** from me. They must write of that monies on my account as none was my fault as I did do the right thing. I stop my stop orders. each stop order that was sent back cost me at the bank R160 plus. I want the account to be closed and monies written off and the R2000 that was wrongfully paid into the account payed back so I can give it back to the owners. FNB deduct the R2000 from the slight over R5000 they claimed I'm in owe to my account.
