VERY UPSET CLIENT!!!!

I AM VERY ANGRY !!! I phoned the customer assistance line regarding a query on my account as i am a new customer to fnb. I switched because i thought fnb would be a better service provider than my previous bank. I spoke to the lady i gave her my id no and me account number and she REFUSED to help me without my card number , it was an urgent query and i did not have my card with me at the time. I said you have an attitude lady and she went on , i said ill F&^%# report you on halo peter she said i dont care she wouldn't give me her name nor a reference number !!! Did i make the right decision to switch to FNB with attitude and rudeness like this ?????
