Useless service at FNB Karaglen

Absolutely useless customer service actually non existant. Went to the Greenstone Mall branch and Van Riebeeck Mall branch (both closed for renovation). Ended up at the FNB Karaglen Mall branch (hopefully the last time I ever have to go there). I spoke to the host and asked her if I could use the tellers to deposit cash as I did not feel comfortable doing this outside. I went to the teller department, there were 2 tellers, a gentleman and a lady. There wasn't any clients in there at all at the time. The gentleman seemed to be cashing up so I went to the lady, explained how I had just come from 2 branches that were closed and would like to deposit cash. She asked me how much and I said R5000. She immediately told me they only accept R20 000 and above but in a very demeaning manner. I understand policies and procedure but customer service always comes first and if it's in line with the policies and procedures then there should be no reason not to assist. I told her there are no clients here can't she just help me quick and she **** to me and said that the system won't allow her to take less than R20 000, I asked her again and she repeated her answer. I laughed at her and said that can't be true. She then said FNB systems have changed. I have worked in the banking industry for a very long time and I know there is no such thing like this. She also proceeded to say that, "there are 4 atms outside it will go quick, we are only 2 in here it will take long." she told me again to go outside and use the atm which I did. As expected the atm spat out the notes twice and I had to swop cash around in full view of everyone. I can't believe this is how they are trained to treat clients. I would of understood and accepted her lie if they were busy and under pressure but she chose to relax instead of assisting a customer. That is absolutely pathetic. She definitely does not belong in a front line position like that. Talk about going the extra mile or putting customers first.
