Very bad Attitude, considering closing my accounts

I am a client of First National Bank. My accounts are with First National Platinum Park Polokwane.<br> The branch involved are First National at Savannah Mall.<br> I make use of the bulk teller on a regular basis at various banks, our company deals with a lot of change.<br> When I do banking at First National Bank, I usually make use of the Platinum branch, but today I had to make use of the branch at Savannah Mall. <br> On arrival, we were told to stand in the line for regular clients and not the line for the bulk teller. The bulk teller were being used to help the regular every day clients. I proceeded to stand in this line. After 20 minutes I ended at the front of the line and on handing my change to the teller, she informed me that she can not help me, I have to go to the bulk teller. Why were I told to stand in this line when I knew I had to use the bulk teller?<br> I refused, why should I go to the bulk teller now, when I wanted to in the first place. The manager then ordered the teller to do my banking. but this did not end here...<br> The teller then decided she is going to teach me a lesson and tried to take as long as possible to complete my banking.
