Union Bank Of India — complaint - cheque clearing delay - omkar abhyankar

Dear sir,
I have saving bank account (Ac no. [protected]) in deogad branch, dist - sindhudurg, maharashtra. I am customer of your bank from last 7-8 years. Nowadays, i am getting frustration with your bank service repeatedly. Sometimes your server doesn’t work, sometimes your people delays the work etc.
I am writing to you to get your attention on one of the most disgusting kind of experience i am getting currently.
In today’s digital era, we expect little faster process of requests, but your bank is failing to serve.
I deposited a cheque of hdfc bank, of mumbai branch, of rs. 19, 000/- on 16th may 2019 in my home branch, i. E. Deogad branch. [cheque no. 000083, bank - hdfc bank], since then there was no communication between me and bank. Sometimes due to network issue, we don’t receive message of balance credit, so i ignored. I assumed that my cheque must have cleared, so i made some payments after 20th of may, but then i came to know that cheque is not credited in my account.
I called customer care o[censored]nion bank on 25th of may 2019. They said that, there is no records of any cheque deposits, neighther there are no deposit requests in system. They asked me to call branch where i deposited my cheque.
I called them on 27th of may (As there were bank holidays inbetween), they asked me several details & finally gave me below reasons for delay-
Bank branch of which cheque is deposited is mumbai branch which takes time to credit. We have initiated service already, but it takes timewe have to send that cheque to kankavali or sometimes to mumbai to clearance. It will get credited in 2 days. (Means till 29th may 2019)
I waited till today, 29th may, but no amount received yet. I called the branch again. They said below things-
Mumbai branch cheque takes more usually this much time to credit (In my case it is 13 days now) it will get credited in 2 days. (Again promise!!!)
I just want to ask you few simple questions-
Even in todays digital era, is your bank this much slow, that it takes more than 12 days to credit a single cheque.??? Don’t you any other faster option? If process is taking this much time, your staff don’t have courtesy to call or message and inform to customer that it is getting delayed. When my cheque is getting credited. I am facing serious issues with funds because of inefficiency of your branch.

I am expecting to get my amount till 1st of june.

I am expecting a strong action against a person, whoever is responsible for this mess.

I am expecting a detailed reply of actions you have taken after my this letter to you.

P. S. I have so many other bank options to simplify our work. But i trusted on your services for years. Please keep some courtesy towards customers and work as per expectations.

Regards,
Onkar abhyankar
