Booking.com complaint: Covid

Tues 28th April to 01 May , red no… 20203599128895, pin 0148.
This holiday was impossible to get to due to covid, my flight cancelled, both countries in complete lock down, booking.com never said a word, never cancelled it just stupidly assumed I went, I didn’t know what to do, so explained to booking.com I needed to change dates, they told me to contact the hotel, I did no problem, the next year same happened again, so this year I contacted the hotel and they said I have to do it through booking.com, but it’s been impossible as it’s gone off the system and booking.com insist I book direct with hotel, unfortunately the hotel won’t deal with me, they insist I book through you, the hotel is ignoring every what I send, booking.Com is just frustrating and keep saying the same thing over and over and not understanding my situation, I can’t and repeat rebook through hotel, they aint listening, your not listening, I am being treated awfully by both, I have booked over 20 places with booking.com and this is how I get treated when I need help, clearly a company which turns it’s back on customers when they need help.
