random calendar synchronization issues (airbnb to hbook)

[Josh1109]

I'm having seemingly random calendar synchronization problems with my my airbnb calendars recognizing and/or overriding reservations from my website's reservation calendar (on Hbook).  The vast majority of my website's reservations are being properly synched and recognized on airbnb, but over the last month I've had 6-7 double bookings allowed on airbnb that should have shown an existing reservation from my website.  There doesn't seem to be any rhyme or reason as to why this is happening.  When I've meticulously gone through all the reservations for which this has happened there's no apparent common denominator amongst them (and it's happening on different units).  On the other hand, my website calendar seems to flawlessly recognize the airbnb reservations, so this issue is only manifesting itself on the airbnb side of the fence.  No identification of the issue (or resolution) yet from airbnb.

I have the same problem since about 6 months. Lately I complained to AirBnB with no result. The case was transferred to the Engineering Department, also with no result. 

Only the fine of $100 was cancelled and I was forced to state that the problem was solved. No, it is not. And an e-mail to Brian did not help either in 5 days. I am very disappointed with the usually well functioning AirBnB.
