Refund complaint

I booked and reserved a room for 03/05/2025 and was given a confirmation code: Confirmation: ***

My plans changed just before the check-in time (14:00pm) so I tried to contact the property to cancel and I was told I need to manually cancel the reservation on my app. I done so and called the property again to request for a refund but the representative told me to contact booking.com and request for a refund. I done so, and spoke to a representative from the Phillipenes who could not assist because of the language barrier. I have heard nothing since and got no call back regarding my complaint. Please refund my money back into my account!!
