FNB CUSTOMER CARE SUCKS!!

IM SO DISGUSTED IN YOUR SERVICE FNB. Yes i do have an account that went to your legal department/lawyers, but yet on my credit report it says ive missed 17 installments which is not true, because there is a debit order for you on my bank account. And to top it all ive wanted to call in to up my payment arrangement. Ive spoken to eight different people and this one keep referring me to that department . Im currently trying to get hold of your revolving loan department, but to no avail no answer there. I am so disappointed in your customer service and i feel sorry for people who bank with you. regrettably i do not have any reference numbers
