Just wait for automatic refund.
In my case Txn Date is 29th and 30th Nov.
Refund Credited on 19th Dec.
I even contacted Airtel VIA E-Mail. Those bustards are asking me to Contact Service Provider/Source Bank.
Whereas Airtel is the Service Provider itself even though they are asking me to contact Service Provider.
On E-mail they clearly mentioned that Utility Bill Payments via Thanks App are Non-Airtel Txns.
Going Forward I am not going to pay any Utility Bill over Airtel Thanks App.
I am happy with 5% Cashback on Axis Ace or SBI Cashback Card.
Airtel App does not even show BBPS TXN ID and In case of failed payment, there is no way to track Payment without BBPS TXN ID and as I already told ,
Airtel does not consider Utility Bill Payments done on Airtel Thanks app as Txns Done Via their Platform.
In case Utility Bill Payments via Thanks app get failed, You will get only inconvenience in return.
