Booking.com not assisting to get refund from their listed accommodation venue

I have booked accommodation at Cascades Suites through Booking.com in October 2021 stay on 31st December 2021 - 04th January 2022 The card payment was unsuccessful then arranged with Cascades Suites to make the payment. I directly paid Cascades Suites almost 70% of my bill. I cancelled the accommodation received confirmation that it is a free cancellation. I received automatic message from no reply Booking.com that to speed up process of getting my refund I must contact the property owner of Cascades Suites(Ivan Talberg) who has been rude to me that his property do not belong to Booking.Com. I have attempted getting help from Booking.com, spoke to (Martin V, Raquel A, Judy Ann A) they requested proof of payment that i provided, when following up being told they will have to wait 15days which was on the 03 January 2022. I did not receive any refund till today, left with frustration and disappointed as I trusted that Booking.com is middle business that will protect and provide customers with business that will not frustrate us. I am hopeless and frustrated without help from Booking.com. Ivan(Cascades Suites) is frustrating me that will only think of refunding me end of January, just wondering of what Booking.com is doing on their side to make sure that i get my money asap. It is unfair to send me solve the problem with their unfair supplier, I am not sure if I must tell my family and friends to trust Booking.com
