Poor service or zero service

I have visited the bank for debit order reversal.stories have been told as I waited long minutes with a promise that my phone call would be attended to but all in vain and a technical problem was mentioned as an excuse,i left this institution that boasting with#howcanwehelpyou without deriving any joy.again today 27 Dec 2018 I visited the bank for the same service and same thing happened.i cannot believe that I wasted my money for nothing,and you know they get their monthly charges for whereas they do not deliver.i was asked again to come again on 28dec 2018,using my petrol.i am so sick and tired of their poor service.
