Sorry you are not correct on this @Claudia2350 ; hotels as well as STRs are refunding money as it's illegal to provide short terms accommodation in the UK at the moment (as your know) for anyone but key workers, those attending funerals etc.
I am sorry you weren't given the correct information by Airbnb's customer centre, but it must be confusing for them as things are changing all the time both in terms of Airbnb's policies and local legislation.
