DH booked a hotel stay through Agoda. He didn't realise at the time that he hadn't received a confirmation e-mail.
We can no longer go, for medical reasons. The hotel has confirmed that we are booked in, but can't accept our cancellation because we booked through Agoda. But we can't cancel through Agoda because we don't have a booking number because we didn't get an e-mail confirmation.
If we don't cancel, we will be charged £700.
How can we cancel the booking?
