Airtel — restore services

Dear sir/ madam,
My father had bought a mobile some four years back and was using dual sim.in that the number [protected] was working till 24th april 2020 but all of a sudden the services for the number [protected] stopped working and even well before the recharge amount expired and eventhough there was time for recharging it we paid an amount of rs.558/- through airtel thanks app via vijaya bank on 25.4.2020.

Kindly restore services for mobile number v. Jagannathan - [protected] as payment was made on 25.4.2020 via vijaya bank. Kindly do the needful as the tower is available at times but indicates that only emergency calls can be done via the number given above. Not able to make calls or use internet.
