Booking.com not responding although the accommodation cancelled the booking

I booked accommodation which the premises cancelled due to the travel ban On booking.com the only option was a cancellation penalty. Booking ref *** The accommodation owner was very understanding and assured me that I will not have to pay a penalty. However booking.com still shows my booking as upcoming and still shows a cancellation penalty on the booking and advises me to contact the premises. My booking is in a weeks time and I am getting frustrated with this time consuming problem
