Unauthorised debit orders, additional charges and failure to assist a client! Appalling FNB service.

Dear FNB, Having been a loyal customer for over 15 years, the level of service received recently has been appalling. 4 unauthorised debit orders, rude consultants via the FNB app and to add insult to injury, the levying of charges due to FNB's failure! Due to the unauthorised debit orders, FNB have levied charges to my account and the consultant flatly rejected my concerns in relation to this and my request to dispute these charges. Further, FNB has failed to notify me of the unauthorised debit orders, and have claimed that they are unable to do so! From a bank which prides itself on putting it's customers first, this is unacceptable.

Please assist!
