Air India Express — PNR-AVCJXF- refund of flight ticket

Address:

ajman, uae

My flight PNR was AVCJXF, it was cancelled by air line itself.
I was informed that refund will be processed in couple of weeks.
now its been more than 45 days but still payment is pending.
I have called call center and sent several emails but nothing has happened.
I always got standard reply which is auto generated one.

appreciate if you can look into this matter and refund my amount asap

best regards
