MONEY REFUND FOR CANCELLED MF ORDERS IN COIN.

I wanted to invest in new Jio-Black rock MF, what happened was I paid once through UPI, Then I invested my funds in liquid funds then I noticed that The Coin app was showing Payment pending, so I paid again
Later I noticed 2 orders were processing so I cancelled one order

Payment for MF Went two times and since I cancelled order, processing stopped and It said “ORDER CANCELLED BY USER”

The thing is I havent still received the refund or anything, It has been quite few days and What I am fearing This happened quite few times before and I fear I lost my money on cancelling previous orders too…Need help guys
