Airtel — Reflecting negative balance in my Airtel wallet

Address:

Rajahmundry

I am using Airtel Payments Bank since 2020 and once I have used my airtel wallet for my prepaid recharge of Rs: 254/-...I added money of Rs: 254/- to my wallet and thereafter I proceeded to recharge...My recharge was successful but my wallet showed negative balance i.e., Rs: -254/- then I received a cashback of Rs : 10/- for my recharge and thereafter I added Rs : 1/- to my wallet and now it showing my wallet balance as Rs: -243/-. On this issue I visited Airtel office too but they were too negligent with touch-me-not attitude.
