Over my time here I have heard of positive experiences in dealing with the Resolution Centre. Maybe once a month there will be a post praising the service offered and received, and I guess Beata, we generally don't get to see the sucessful outcomes. Few people actually thank the insurance company for fixing their car...it is sort of expected!
On one side, the Resolution Centre has over the years become bogged down in minor issues, and has been forced into progressively becoming a more hard line 'damage minimisation' arm of Airbnb.
On the other hand Airbnb is a booking site, and despite some fluffly statements is not an insurance company! Most claims are made with a certain amount of emotional angst involved where patience, (while Airbnb get a balanced perspective on who is at fault) can be extremely limited.
I have never had to make a claim Beata but all I can suggest from reading what has been reported here is, read all the rules around issues dealing with the resolution centre and set yourself up with a proper protocol so that if you are unfortunate to have another occurence that requires assistance you know the accepted way of reporting, the time frame, and format required for the Resolution Centre to make a favourable decision. Cross all the t's and dot the I's and don't give them any escape path from your complaint.
What you have to remember Beata, guests make Airbnb money, the host is the neseccary evil to facilitate making that money. They will rather side with a guest than a host!
I am sorry for you that you feel you have been hardly done by where the Resolution Centre is concerned, and I know nothing of the issues which have lead you to feel that, but good outcomes are possible, you just have to make sure the scales are weighted in your favour. Airbnb do not offer 'no fault' insurance!
