Access to calendar and accounting files after closing account

[Michael9230]

We had a property manager for our airbnb.  We only had access to the calendar and nothing else  (he made us cohost with calendar access only).  

We are supposed to receive our final  check soon so  we wanted to double check the calendar. 

However, he said we now no longer have access as listing has been taken down. 

How do we get access to the calendar and record of who stayed when and what he charged them as well as any other info for taxes etc?.
