FamPay KYC Failed Because Aadhaar Is Linked to Another Account

I have been facing an issue with my FamPay account for the last 8 months because my Aadhaar is already linked to another FamPay account. When I try to complete my KYC, the app shows an error saying “Something went wrong” and “This document is already linked to another account.” I contacted FamPay support regarding this and they told me they cannot do anything, or that I need to complete a new KYC to update it. I am not able to change or update my Aadhaar within the app and this is stopping me from using FamPay properly. I request FamPay to help me change or update the Aadhaar linked to my account, or to unlink it from the other account so that I can successfully complete my KYC and use the service without any issues.
