Fairmont Hotel Washington DC review: Mother's day cancellation penalty

My wife got sick so we four could not attend Mother's Day brunch. We were charged the full amount anyway by Heather.[protected]@fairmont.com. We want our $393 refunded as we did not enjoy brunch. The hotel [protected]) is not willing to refund the money and not returning our calls. I spoke to Heather on the phone who said she would talk to her boss, despite her being the restaurant director, yet she did not follow up and we have a bill on our debit card.
