Booking.com complaint: Booking number 3806378079

I was book 3806378079 during booking make full payment for e wallet. My booking was comfirm, I request additional guest to stay in, be inform addition cost 15 euro per day so total 30euro will be extra . I agree it, I have check with my bank credit card no booking.com transactions be charges during 9-10102022, my credit card was no problem for 30 euro, after booking.com sending me a email Eventually that day I very busy not open my email so the booking automatically cancel and penalty my 65euro and be told the 30euro I need to paid, I feel unfair without staying the hotel, because of booking.com system cancelled my booking make me lost,
1) I have call my bank my card was no problem, no booking.com transactions be changes and rejected, my credit card payment show same date others payment gone true, so I comfirm is not problem from my Card. At your booking. Com at the same time I book another Italy hotel booking no 2988907709 also request for additional guess be charges 80 euro extra , why booking.com can charges my card at 5102022 payment was successful.
Why my booking 3806378079 not successful please explain?

I ask my Italy friend call Hotel, hotel not going give waive of cancellation due to cancel is by me at the system show! Why is me? Is, booking.com system

Here I wish you can refund my 65 euro e-wallet and 30 euro without additional charges because I never get to stay, and I need to paid for 95 euro. hotel have say not received any payment from booking.com , Because on 1110 after booking.com unable to contact hotel, I have make a reservations at trip. Com for same hotel and date I make full payment.

Disappointed for booking.com service not protection customers using your service. Customers is bingger lost if happened like, my cases, never happen since day 1 using booking.com. pleased do your best I not going take this lost! Because the booking is comfirm instead asking upgrade another person, end up penalty for 95 euro for no reason.
