Axis Bank — Stop ECS mandate

I have given a form to stop ecs mandate on 2nd December 2021 at Noida Extension branch but unfortunately branch didn't take any action even I made many visits to the branch they said it will stop, its on processing, etc. It's almost month over still no use in visiting the bank. Also cheque return charges of Rs. 1300/- each has been debited from my account every month for that also they didn't provide any clarification. I think it's better to close the account with Axis bank have a account with some other banks.
