Unfair treatment of guest - booking cancellation

I had made reservations for 2 Family Rooms telephonically. One of the reservation number is 299338002 [26/07/24-28/07/24]. When making reservations, I was told that I could pay on arrival using my credit card. On the eve of my arrival I received an email that my reservations were cancelled due to non-payment. When I enquired, I was told that the hotel had sent me an email. Sadly, my family's plans had to change. Unfair treatment and very unprofessional!
