Bad Service

My wife was planning a weekend away with friends and family to celebrate our anniversary Date for booking on the 22 -24 May 2020.

Booking was made on 11 February 2020 but was cancelled on the same day. My wife WhatsApp the owner name Stephan on the 12 February 2020 but no reply. She also sent him the bank details to do the reversal of the money his responds was that he will get in contact with booking.com to do so but its now two weeks later and still no money in my bank account. Stephan even said that we could deal directly with him. I called him again on the on the 25 February and he said he will find out at booking .com why the money haven't yet been reversed and I had to call him back an half an hour later but called but no answer. I called on the 26 February ,his reply via message was busy cant talk and again I message tell Stephan that he is messing me around and still no reply once again.
