State Bank Of India [SBI] — Server issues which resulted in financial loss

I had to transfer money to my other bank account where i did it through my UPI where the server is struck and the payment has not been recieved by the beneficiary as well as the payment didn't come back to me which resulted in a default payment and my credit score. This isn't the first time where I'm facing this issue and due to this many customers from this bank aren't happy with the services which were provided by SBI and the branch staff where i stay is full careless and moreover they have no idea what they are upto. Whenever if they cannot resolve an issue they come up with the so called the official slogan of "SERVER IS DOWN AND WE CANNOT ACCESS YOUR ACCOUNT" have no idea where SBI had no server at all. And the manager who sits in a Fully comfort place states as if he isn't responsible for anything and moreover he has no idea when he visits the branch and as soon as he comes the first thing which he does is to ignore customers and go for a smoke. I really don't want to raise this complaint but since after seeing all these things made me do it. I want a clear answer for this and I'm even ready to reach out to the higher authority as well. Hope this complaint alerts some as it's high time that SBI or RBI should take an action for.
