Bank Of Baroda — 'account not found' error in every application

Address:

Agra, Uttar Pradesh, 282005

Respected sir/madam,
There is to inform you that i've been facing the problem of 'account not found' everytime when i try to access my account through mobile banking applications or upi and because of this i am faving difficulties. I have had visited the branch office many times but they don't even showed any interest. The head branch said that my account is not linked but even after so many visits no concern is shown.
I am so disappointed with your customer care services. Kindly show some concern or i have to close my account in your bank.
