Dear Celeste, as you may read below we have dozens of satisfied customers and guests review, everything have gone smoothly with them, they paid their security deposit on arrival with their credit card, they received the deposit refund after departure and they presented the copy of their ID or passport on arrival. All this procedure is MANDATORY BY LAW, and I guess you are not going to be able to change this law. Every guest has to be registered with a copy of their passport. Airbnb is not managing the property nor handing your ID to the local authorities, which is our obligation, I repeat. All you write above is completely out of sense and have no base.
You could have contacted us directly if you had issues at checkin and not airbnb, which is not responsible for the checkin procedures. We have an agreement with them since september 2013, and so do many other listings have, that we are entitled to collect security deposits on arrival using the client's card on our POS terminal. It is a practice valid in any rental condition, for boats, cars, hotels, bikes etc. Nothing that should surprise you nor alarm you.
With your aggressive and alarmed attitude you have generated a situation which may lead to our account closing and as consequence make impossible to many airbnb nice users to enjoy our venues that we deeply care of and we struggle to improve them day by day.
Your deposit is under hold first because WE DID NOT RECEIVE ANY PAYOUT FROM YOUR RESERVATION, and second because a lock of a bathroom door was removed and disposed off. That lock is an expensive lock.
We really suggest that you contact airbnb yourself and try to make the things work, suggest them to pay us our full payout and we release your deposit minus 80€ for the lock.
