Boat — I didn't received any amount of my refund

For the first time I have ordered boAt Airdopes 402 white on 6th July 2021, on 12th July got the product but it was defective, the right earbud wasn't working even I have tried to restart but nothing has been changed. Next day I register a complaint in boAt for replacement, as I bought the product from boAt website, so they approved and on 13th July they took the product and on 18th July they mailed me that the product is now out of stock so they will refund, but they have refund the value in Payumoney, after that I have linked my bank account still the Payumoney didn't send me 1 penny, the Payumoney website is a worst company I have ever seen. Overall I'm very much dissatisfied with the experience.
