FamPay Selfie Verification Falied

I am facing a problem with selfie/KYC verification on my FamPay account linked to mobile number 83672006**. My FamPay account is currently linked with my sister’s Aadhaar number. When I tried to complete the selfie verification using my own selfie, the verification failed and my KYC was cancelled about one week ago. Since then I have not been able to successfully complete the verification process. I contacted FamPay support about this issue but I did not receive any response. Because of this, my account remains unusable even though I am ready to provide my correct details and complete KYC properly. I request FamPay to update the Aadhaar on my account to my own Aadhaar details and allow me to redo the selfie/KYC, and then approve my KYC so that I can use my FamPay account without further issues.
