Goamiles — Refund not received after 2 months

Address:

Goa

I have a refund request with goa miles since 21st April, 2021 and today it's 1st June and I am still waiting for my money.
I am calling on the given number again and again after 4/5 days to keep follow up with them and on each call I am being told that my refund is in process and they have put it on priority basis bit still after waiting for one and a half month it's not done
This is the worst customer service experience I have ever had.
What on earth will I have to do get my money?
The customer care people have the audacity to tell me that that can't forward the call to any senior person as they are not available.
Today is 1st June and again I have been told that WITHIN A WEEK I'LL GET MY REFUND.
