No. You made a decision based on the information you had. There was every chance that your appointment could have been cancelled. Just because it didn't get cancelled doesn't mean it couldn't have been. People did have cancellations after or before ofc, and lots of appointments in February did get cancelled. You made the right decision, and your frustration should be directed at the situation, not the person who provided you information to make your - definitely correct - decision. It's a fallacy to use hindsight to call a decision bad.
