Bad attitude and poor customer service

I went to the bank at around 13:15 pm on Friday, 15/05/2015 to make a deposit and I was assisted by the above mentioned teller. The lady looked so grumpy/irritated or maybe annoyed, then she took my deposit slip and looked at it and she realized that I had coins and asked ***orker who was busy with another customer whether she should take my deposit or not. The ***orker told her to take my deposit. My coins were in plastic money bags and packed according to denomination stipulated on the bags. The teller started to count my coins but she didn't seem to understand what she was doing. She kept weighing the coins repeatedly and throwing them on the scale with an extremely unpleased face. She took long and started to remove the rubber bands to scale the coins bag by bag. I was fine with that but I lost my patience whe she starts to take coins out of bags and put them in a big bank bag as I realized that Its going to take longer and That wasnt necessary.Then another ***orker came to assist her by counting my notes and I asked him to call the manager as I wasn't happy with service. He just rep**** by saying that is how it works and no manager was called. It took 40 mins for one deposit.
