1mg — Didn't receive refund of order

I placed an order from 1mg and I paid from Amazon UPI. I cancelled order, but I didn't receive refund from 1mg. I talk with 1mg customer service they said that you will get refund after 10 days but still I didn't receive refund. And I talk with Amazon customer care they said it is transaction from bank to seller we can't do anything. Please talk to bank or Amazon customer service ya 1 mg service. Please solve this and initiate refund.
