[Resolved]  EaseMyTrip.com — Refund not received for canceled tickets

I had booked a multi-city ticket with Booking ID: EMT80746472 from
1) Nagpur to Delhi for 25/04/2021 in Indigo, PNR: QHWMHF
2) Delhi to Jammu for 25/04/2021 in GoAir, PNR: H3SHYY
3) Jammu---Delhi---Nagpur for 28/04/2021 in Indigo, PNR: DL3GUW

Due to Covid restrictions, the flight timings got changed and I had to cancel all the tickets with the Airline. I have received confirmation of ticket cancellation with full refund from airlines over email. The Airline company said that the refund would be made to the agency from where the tickets have been booked and that the refund has already been processed from their end.
Upon submitting a cancellation/Refund request with EaseMyTrip on April 19, 2021 I was assured that the refund would be made within 7-10 days.
I have received refund against just 1 PNR(QHWMHF) out the 3 PNRs booked under this booking ID.
When I call them and ask for updates, they only say that there is a technical issue and the case been escalated to senior team, but wont give me any details about the issue or any timeline for the resolution. Whenever asked for correspondence with senior member, they say that the call back has been scheduled and I'll receive a call back from their team with few hours, but never have I received any calls.
The EaseMyTrip customer service team is not helping in resolution of the issue and it has been more than a month and they are still giving the same excuse.
Request you to please help in resolving this matter on urgent basis and refund my full amount as soon as possible.
PFA cancellation confirmation mail from Airline.
