Indigo Airlines — Refund nor processed even after 20 days of PNR cancelation!

Even after numerous phone calls and innumerable emails, Indigo airlines has not refunded the amount against a canceled PNR FYM1UQ. The Refund transaction ID BMBK[protected] given by the phone and email support are also different! I want the airlines to compensate me for the amount of time, energy and money that made me spend trying to get my money back!
