***** ISSUE - IMPOSSIBLE TO CONTACT BOOKING.COM

I have had a ***** booking made against my credit card. But trying to contact them to report is impossible! There is no general email address and can only use a past booking to contact them which is not correct or fair. Their website provides no good way to contact them therefore they are avoiding any way for their members to claim a refund. Just appalling and recommend others to not use Booking. com to avoid this ***** scenario as I have. No way to claim back thousands on a booking made to my credit card I did not make.
