Subject: Request for cancellation fee waiver or date change

Dear Property Team,

My Booking.com reservation is for [property and local stay dates].
I understand the cancellation terms shown in my confirmation.
Because [verified reason], I cannot use the booking as originally planned.

Would you consider [a cancellation fee waiver / a partial refund / a date change]?
My alternative dates, if applicable, are [dates].

Please confirm any approved amount, currency, additional price difference,
and the terms that would apply after a change.
If approval needs to be recorded with Booking.com, please advise the official procedure.

Please do not cancel any remaining rooms or nights without confirming the scope with me.
Supporting documents: [file names].
Thank you for your consideration.
Kind regards,
