Mytrip.com complaint: Ticket Refund Delay(UN5LXE LACY2G)

We have not received our ticket refund yet. We have contacted the airlines and they clearly told us that they have processed the refund from their end long back. But when I contact your team, it us the same answer I get and there is no update in your tracking system too, it was updated last on 18th August.
Also, I would like to mention here that one of our friends, with a similar situation has got their refund already. Why is the delay happening for us?
I am sorry to say but if there is no response from your side I will have to raise a complaint with the airlines about the internal travel agent feedback.
We have undergone grievances because of your delay, like:
1) our primary trip to India got cancelled and could not reunite with family after such a long covid break.
2) children are very upset and their vacation got wasted.
3) could not make any alternate travel plans because of the money that is locked.

I am writing this after so many attempts of contacting you and the monotonous response that you have been giving. Please understand our situation and refund our ticket amount ASAP.
