Refusal to amend booking

I had a reservation with this hotel, I was supposed to check in on the 9th of August, I did my reservation on Booking.com. I called both of them to amend the booking but I could not get help. I told them that the the very same people I was supposed to travel with contracted COVID. None of this two companies is willing to help I think they suggest that I travel with this people as sick as they are. I have never seen this heartlessness in human kind. The place where I payed my money and expecting superior services.
