Sandwich Glass Museum review for Appointment Booking App Propel

We've been running this app for well over a year, it's been reliable and fills our needs. We recently had an issue with someone not being able to make a booking, and within 10 minutes support had looked into it for us and suggested that we check our Google Calendar - sure enough, someone had placed a block on Google which we didn't want. Good customer service, good app. Highly recommend.
