Hi, team, i tried multiple times the recharge and not getting the refund back to my credit card. Airtel is holding my money.

I am not able to do the recharge as well no one is supporting including call center agent, lead, supervisor...

Talked to customer care many times and paid for the call charges as well details as follow:-

Ref no conrc[protected] date 26-aug
Ref no cbnrd[protected] date 26-aug
Meanwhile, i went to retailer as well
Ref no cbnrv[protected] date 30-aug morning
Ref no cltnm[protected] date 31-aug morning
Ref no clapd[protected] date 31-aug evening

Looking for number portability options, even ready to pay more call charges but services should be better... I am struggling since 26th august

Their representative never calls back...
