Hey there, equinox001, I'm sorry this happened! I realize this would likely be frustrating or confusing, as your extensions have been automatically been redeemed in the past.
Looking at emails Angels received with the old rewards redemption structure, the email states the membership will expire on a specific date, meaning the rides on that date would not be covered by your membership. That said, I appreciate your feedback regarding the time of expiry, as we are always working to improve the rider and Bike Angel experience, and that includes support experiences!
I hope you'll return to the community here should you have a question or concern in the future. 😊
