Airbnb cancelled booking and show cancelled by host.

[Vishal53]

I was having a confirmed booking,

When the guest arrived at the apartment, he started saying that it is not the same apartment and walked away from the apartment.

And raised concerns with Airbnb support. 

Airbnb support contacted me and asked explanation for the same I have told them it was not my fault and submitted all the evidence that the guest was taken to the correct apartment and it was clean I have sent all photographs with date and time.

And asked to send me to share evidence submitted by the guest. they haven't done it by saying they need a confirmation from the guest.

And then they have canceled the booking and marked it as it is canceled by me. and Cancellation charges are applied to me. 

Can anyone suggest what needs to be done in this case?

You need to open a ticket with Airbnb and say you never agreed to refund the guest voluntarily.

also report on their social media @Vishal53

And stress to them that you never asked for or agreed to the cancellation and you want all cancellation penalties removed.
