property 7941388 - Closed/Not bookable

My property 7941388 looks "Closed/Not bookable".

I try tu change this condition but it is impossible.

When I try to change, platform ask me to confirm my location and that I must wait a BOOKING.COM code that will arrive by postal mail.

I did many times but never arrive any envelope.

My property is blocked and I cannot resolve

How can I resolve this matter?
