Airtel — broadband activation fee refund

Address:

560043

I have paid activation amount of rs. 500 on 30th dec. Transaction id [protected]. I have not the broadband connection yet. Raised refund request but no reply from airtel team.
The sales team after getting the payment are not picking up the call. Totally, unprofessional services from airtel. Waiting for resolution till now with no reply from the airtel or any airtel person
