Deutsche Bank India — wrong account number details(by bank) leading to money transfer to a different account

I was supposed to get INR 56819/- from my employer (Robert Bosch) bearing the
following details:
Name: RBEIEPFTRUST
Acc num:[protected]
IFSC: HDFC0000523

Few months back I had taken a letter from Deutsche bank stating my account details. Unfortunately, the account details mentioned by the bank in the letter is incorrect.
This lead to the account details mismatch and the amount got credited to the wrong account instead of mine.

My account number: [protected]
Wrong account number: [protected]

To make the situation worse, I haven't received any support from the Deutsche bank customer care even after mailing them a number of times.
