Cancelled accommodation without proper communication

Booking.com cancelled my booking for accomodation for out holiday and just sent an email, considering that as proper communication. Two days before the booking I checked to find the booking was cancelled. Logging onto the Booking.com App, it still indicated the booking as confirmed. Only after I click in the booking, it changed to cancelled. The booking is now for peak season and I won't find alternative accommodation as well as other costs for transport and confirmed leave scheduling at work which is now a total catastrophe! This is definitely not acceptable! Phone me if you decide to cancell since my leave need to be booked in advance for the following year at work!!!!
