Airtel — Refund not being initiated after repeated requests ||[protected]

I was forced to opt for a refund because airtel technicians stated my area was not serviceable. Hence request for cancellation was raised on 6th April and l was asked to wait till 21st May and still refund is not initiated. I would like to understand why an initiation of simple refund takes 45 days and after that no step taken about it. After that l was informed that it is already initiated by NEFT and the amount should be credited within 15 days. It is already over 20 days no payment received and no executive is even bothered to reply back. I even attached the bank statement showing proof where amount is not credited.

Thank you
