Back in January, I booked to stay in Hotel Disneyland Santa Fe in March (in Paris). Due to the effect Covid-19 has had in everyday life and travel, Disneyland Paris had to close including the hotels for guests who were not there at the time of the closing down decision. I contacted Booking.com 5 days before my stay at the Hotel and explained the situation and they said they would get back to me in 24 hours.
In the meantime, I contacted the hotel and they said that I should only deal with Booking.com as it's their booking to manage. The hotels in Disneyland Paris also announced that for the visitors affected they would offer either a full refund or a chance to reschedule for a later date whilst keeping the same charge for the rooms as the ones in their original booking.
Now Booking.com says that since the reservation wasn't cancelled beforehand and they're unable to cancel it after the arrival date has passed, they can only offer me half of the money back. I should note that on my initial phone call with them I wasn't told to cancel the booking or do anything for that matter, as they would have to investigate the best way to resolve this.
The booking was made using my credit card, but since it was made in January, I'm now out of the period that I can ask them to step in and withdraw the money and return them back to my account.
Is there anything that I can do at this point to make sure I get my money back for a travel that I was not allowed to make considering the hotel was not accepting guests and the French government was cancelling my Eurostar trains at the same time (Eurostar, by the way, has issued a full refund since my trains got cancelled). Alternatively is there any official route to report this behaviour or complain about it?
I live in the UK if that's relevant at all.
