FNB Pathetic service - 4th month!!!!!!!!!!!!!!!!! struggling from March with this!!!!

I'm struggling for the 4th month now with debit orders not going off on time. or my dates that just is changed without my permission. I did hello peter FNB 2 times now. a lady helped me to change my debit order back to what it was years ago. I cannot get hold of her or someone at credit card division. My debit order did not go off but states that I'm owing money. can someone just please assist me. i'm so sick of this bad service. the previous month that I phoned i had consultants laugh at me while i was waiting for assistance, she bad mouthed me and laughed with her fellow employees while i was waiting for her feedback. She never picked up the phone again to help me.I'm so disappointed in FNB. My service was never this bad. Please assist me. This past few months i was phonong and phonong and went to the branch. still messed up debit orders and dates. Last month my debit order went of two times!!!!!!!!!!!!!!!!!!!!!!! nobody ca help me cause my card is in arrears now.... the debit order did not go through as per request to change it in the beginning of may!!!!!!! there state that its due 4June but no debit order was put on my account! im so sick of this poor service. my first review was in March 22nd. Is there no competent consultant out there that could help me.
