DISGUSTING ATTITUDE - SERVICE NON-EXISTANT

Experienced disgusting service at your standard bank Northgate branch. Enquiries teller named Kato Ravele at 11:45 today. Possibly the most unhelpful, unfriendly, lethargic service we have received in a very long time. We went in to have a monthly limit changed. We still don't understand the procedure as Kato seemed too lazy / uninterested to explain it to us. When asking us anything she was dismissive and annoyed in her approach. Once everything was complete she didn't even bother to tell us - and we stood at her counter for quite some time before she asked what else we wanted. No thank you, no goodbye. No acknowledgement of us being there at all - Disgusting! I'd like to know what you are going to do about this?
