IS BOOKING.COM A SCAM

Ref:236856218 I made a booking on the 24/09/2021 at Sunny Large Indoor and Outdoor Living Area using booking.com and once I made the payment I received an email stating that they were unable to accommodate for the date i requested which was 24/09 -26/09/2021 and I assumed i would received my money back and now its been 5 days and i have not received my money back. i made a call to booking.com on the 27/09/2021 of which i was promised that the funds would be paid back to my account and even i called in today 29/09/2021 and now i told i have to wait 7 days for my money. now i feel like booking.com is a scam
