Poor refund processing

Unfortunately I made a double booking for a flight via booking.com. I was told that I need to fix the problem with the flight company by Booking.com. I spoke to the flight company and they actually refunded the money to Booking.com as the agent who made the booking. But now Booking.com is taking its time to refund my money. I’m told to wait and I have been waiting for 4 weeks. The flight company refunded the money to Booking.com on the 2/2/2023 and I’m still waiting for Booking.com to this day
