Makruzz Pvt Ltd (mak Logistics) — Booking cancelled but money not refunded

Address: Makruzz pvt ltd. Address : MAK LOGISTICS PVT LTD 2nd floor, GATI Building #99, J.N. Road Delanipur Port Blair - 744102 Andaman & Nicobar Islands

Website: www.makruzz.com

I had made 3 bookings (For 2 people each) via makruzz (Private ferry company in port blair), with the following booking ids :
 "fehrpa, qfyoen & ebypan"
These were for port blair to havelock (9th may), havelock to neil island (11th may) and neil island to port blair (13th may) respectively.
Due to the dangerous covid19 situation in india, i decided to cancel these bookings and made request for cancellation on 20th april, 2021. Makruzz responded by saying that barring rs 118 per ticket per person, the entire amount will be refunded. This makes the refund total rs 10920.
I waited for refund and reminded them several times over mail, but every time they kept giving false assurances. Some days later, they even stopped responding to my mails.
My rs 10920 refund is still not processed, and it has been almost a month since i cancelled my booking. They are not responding over call, whatsapp or mail.
Whatsapp number : +[protected]
Please help to get my refund back at the earliest.
I have attached the entire mail chain for reference.

Thanks and regards,
