FNB is concerning me in terms of security

I have had a FNB One Account for many years. I contacted my Premier Banker in January advising that I noticed something strange after using my credit card regarding ebucks. He came back to me and advised that the account was never aligned ( what ever that means ). I had him sort out the account and now using my new Creidt card, only to find that all purchases for January and February were never allocated for eBucks! FNB has messed up my account big time. Why watch out for phishing and ********** when FNB cannot solve things themselves! If you cant look after my monthly earnings, please say so no, I will rather move to a more secure bank
