Mcdonald's India — Refund issue mcdelivery

I ordered from mcdelievery on 6th November via amazon pay, I ordered thr product twice, money got debited 2 times but order was not placed, so I called the mcdonald restaurant to inform them, they said order has not came to them, so they cant help me, when I checked the mcdelivery application payment history, my order existed there. It was upated that it will be refunded in 2-3 days.. so I waited for 3 days, but I didnt got any refund so I emailed them with this, they asked me wait for 3 more days, i will my refund so I waoted 3 days more, but still no refund. I again contacted them via email. They said we are looking at issue will sort it out soon, but its been around 10 days and they havent solved anything.
