After years of use my beloved Genbook calendar system was bought out by a marketing system Booksy. My longtime clients downloaded the Booksy app at my request but then Booksy failed to provide ease of use. The system would continuously buffer and never get to the point of granting a confirmation code. One client videotaped her attempt to book through Booksy and SIX minutes into the process it still hadn't gotten her credit card information. What NEW client would have stuck with it after twenty seconds of buffering much less six minutes? Then, customers showed me screenshots of a message they received "this business is no longer available" when ALL of my appointments were available. This led them to believe I had closed. That was the day I canceled Booksy. The cancellation process is a nightmare. I'm still not out of their business DESTROYING clutches.
