Address:

ONGC, BKC, Bandra, Mumbai, Mumbai City, Maharashtra

Sir,
With reference to wrong billing to the tune of rs 9176, 61 as interest +gst+sgst since april 2019, i wish to submit the following:
The bank has acknowledged the wrong billing and the dispute.
Further they are not ready to review my case since april 2019.

I humbly request you to kindly review my case since april 2019. If i am at fault then no issue, but bank representative told me that it is your fault as to why you did not raise the issue timely. That was my mistake i had already agreed to.
Secondly ineed reversal for rs 9176, 61 subject to payment of my september fill amounting to rs 46696, 73 in full which contains gst and sgst.
I have submitted all the required document to the bank for review of my case.
I humbly request you to kindly raise the issue with the bank so that the bank settles the dispute
If required i will provide the documents to you as well
U p singh
