Fampay Account Access Lost Completely - Want To Recover It

I’m a FamPay user from Dehradun, India, and I’ve lost access to my account because my registered mobile number has been permanently disconnected. I can’t receive OTPs, access my funds, or cancel recurring payments like Spotify India, which continue deducting money. I contacted TriOTech by email and received a reply asking for an external UPI ID. Of the options provided, I only trust the third person, but his old UPI ID has been deactivated. His new UPI ID is 777vis***-1@okhdfc. Please arrange to transfer my remaining balance to this updated ID and help me resolve this issue. I’m ready to provide any KYC documents needed to verify my ownership. I need a clear response and a prompt resolution.
