Corporation Bank — unethical behaviour of bank officials

My grandfather mallappa masane had deposited rs 1 lakh (Kcc / 60/[protected] at the corporation bank vidya nagar branch of hubli on 13th june 2014. After one year, he shifted to belgaum and submitted an application for transfer of the deposit and sb account. The bank officials took the original certificate and passbook at that time. But due to some technical reasons, they did not issue a new certificate. After 2-3 months, documents were misplaced in the bank.
Last year, when we asked for the deposit, they claimed that we had received the deposit amount. They even refused to disclose the details of the account to which the deposit was put into, and told us to inquire about it at the branch where the account was first opened.
On september 18, 19 of 2018 my father again went to the bank to inquire about the deposit. They again claimed that we had received the deposit amount. Even the chief manager chandrashekhar kadiyal claimed the same.
After listening to all this, my father visited the hubli vidyanagar branch, where the officials figured out, with full cooperation, that the account is still active and the deposit amount has not been received by us. We are very much thankful to the hubli officials. Still the belgaum branch officials say we have to look into it and may take a few days.
They have been troubling us for the past three years giving reasons of technical issues. They even have the original certificate. We are suffering a lot because of these irresponsible staff. We also lost a lot of money for the up-downs through buses. Kindly take disciplinary actions against these trouble-makers and compensate us accordingly.
I hope you will do the needful as early as possible.

Thank you.
