Dissatisfaction of service!

I am extremely disappointed and shocked by the fact that the owners of this property would rather put people's lives at risk than make an informed decision to make sure that everyone at their property is safe. We booked for the 29th of Jan, everything paid up. Unfortunately, 3 of the people I was supposed to check-in with contracted COVID19 and I took it upon myself to advise the owner/host of the property. I kindly requested that they allow us to reschedule our trip, not cancel but reschedule because we didn't want to put anyone else at risk. They asked for proof which I forwarded (COVID19 results stating that they tested positive), upon seeing the results they refused to reschedule our trip and they won't even refund us. Now, it beats me why they would ask me to share confidential information with them when they know very well that they would decline my request without even giving me a reason. It really makes me wonder if they even care about their guest's safety.
