Bad service! !

I went to the fnb in voortreker rd .the small one,i think fnb easyplan. I wanted a letter to confirm my account but they needed n id or id copy.i went to get n id copy n went there, waited on the queue then i got the th consultant hu told me he can't do the letter only the lady he works with can. And she wasbbusy with sum1 already, i askes if she couldn't just quickly give me tht letter but she said she is busy and I'll have to comeback . But i really couldn't understand why she failed coz it doesnt even take a minute!! She was so arrogant! Pity i dont know her name and i work opposite them ,so she better come and get my id copy and get that letter coz they want them at work. And i dont understand y the other guy wasnt able to help
