Airtel — Issuing new SIM on existing number

I lost my phone few days back and obviously the inserted Airtel SIM with that.
Visited Airtel Store in Prayagraj (Sulem Sarai & Civil Lines) and the support executives submitted SIM swap request multiple times (using Aadhar, PAN, DL) but everytime Airtel rejected this request stating the reason "Live photo does not match with live photo". Now no one has any clue what's the issue and resolution here.
They are asking me to visit Bangalore where the SIM was first issued.
This is really absurd that there is no communication between two circles (UP & Karnataka) of the same company who happens to work in communication domain only...PATHETIC!!!
This mobile number has been in use with me for over 6 years and it is the only number I have. All my bank account, aadhar etc are linked to this number.
