Hi Sir,
RBL bank has changed my contact details without my request or consent. Due to this instance I'm unable to get it blocked or use. Also I have issue with regarding the annual charges. I have raised so many request to block my credit card and for termination service but did not receive any update. RBL is still sending annual charges statements despite of my termination service request and not responding.
Due to change in my phone number, now it's increased of risk areas of misuse of credit card.
Please assist.

I raised this issues on Dec 20, 2020, 7 Feb 2021, May 27, 2021, Jan 18, 2022.

Thanks
