Razor pay private limited - Refund not received

I placed an order of **, *** rs on a Bombay based website Mainstreet Marketplace on the *th of December and because of the unavailability of the item, my order was cancelled and a refund was initiated the very next day. It’s been ** + days now and I haven’t received the refund. I have contacted the merchant as well as my bank and according to both of them, the payment has been stuck with the payment gateway which is razorpay since then. It’s been days and I haven’t received any kind of help from razorpay’s side besides a few automated emails. The refund status only says ‘Processed’ and that’s it. I request a quick refund as its a hefty amount. I’m involved in the reselling business and because of them withholding the amount I lost * opportunities with clients and suffered further losses. And not even mentioning how much toll it has taken on me mentally as it has forced me to take loans from people as well. I request you to help me get my hard earned money back.
