All credits that were awarded from Shuttle are still valid and are redeemable toward future Tesloop services.
Credits were awarded for numerous reasons such as not showing up for a trip and cancelling 24 hours or less before a trip. Credits are only redeemable toward the price of a service not for charges such as Security Deposits, post-trip damage, citations and tickets.
Your Tesloop Concierge will ask for your email that the credit is attached to.
