unfair cancellation charge

[Jack99]

I've recently been charged what I think is an unreasonable amount.  I've previously had nothing but good to say about AirBnB but this latest episode has really shocked me.  Some friends and I wanted to have a weekend in Ibiza at the end of June.  A friend, using AirBnB  for the first time booked a place without discussing it with us.  It was for the wrong weekend and not something we had agreed on.  He cancelled within 48hrs and with still nearly three months to re-book.  We were charged a total of 676GBP including an Admin fee of 158GBP from AirBnB.  I totally understand hosts wanting to discourage any cancellations, but this was hardly last minute and would have quickly been re-booked by someone else.  All AirBnB will do is offer 100GBP off our next booking.  Is there any way to appeal to this? Or does anyone have any advice?  Thanks in advance.

@Jack99  Talk to the host.  Many hosts will agree to give you an additional refund if they can rebook the dates you cancelled.
