Mcdonald's India — Refund not availed even after 5 months

I purchased food from them amounting to 467.26 rupees on the 16th of September 2023. My first payment went through but the person working the till told me that it didn’t go through. He said that I’d get my refund of 467.26 rupees and that I have to pay again. So I did. But the problem is that I never received my refund back. After about a month or so I sent an email to McDonald’s as well but there was no response from the Delhi branch. And now after a wait of more than 5 months, I am filing a complaint here.
