Incompetence mixed with a bad attitude!

Having a French passport, I have swapped foreign currency more times than I can remember over the past 12 years or so. Today was no different, I arrived to a very unfriendly teller named Thelma Mashele who refused to swap the curreny as she wanted a proof of residence. After I told her that i have an FNB personal account plus a signatory on a company account, she still refused to help. Luckily that I know Antoinette in the branch who took me back to the teller and got her to change the currency as the teller was incorrect in refusing to help me. The worst part was the time it took and not once was there an apology from the teller Thelma who was obviously wrong and doesn't know how to deal with such transactions. Right until the end of the transaction she had a bad attitude and asked me to sign docements etc. with a brash one or two word sentence. Terrible service and as mentioned above the tellers attitude and manners leave a lot to be desired. Perhaps next time she should first find out how to do a transaction if she doesn't know how to and learn a little bit of customer service. Very disappointing
