Worst Service and not customer Centric at all

My worst experience with frontline staff in a bank ever. Visited a branch on 4 occassions waiting for more than 30 minutes every time. Literally 1 active person assisting in the branch whilst 20 others are awaiting to be attended to. Customers given a waiting period of 30 minutes however being helped way after. Tellers are closed for long periods whilst others walk around the branch inactive. This after trying for months tochat to private banker to assist with a Business Account. No answer trying to call them and no responses to emails. I would definitwly not recommend this bank to anyone
