I purchased the intro to snorkeling class. When I tried to schedule a time to take the class the person I spoke with acted as if they never even offer the class. When I asked if they have plans to schedule one soon they again told me that they do not know when they would hold one. They told me they share the pool with the scuba class. Hey! If you don't actually have an intro to snorkeling class,or you do, but you never schedule one, then why do you offer a Groupon for one? Very disappointing. I have contacted Groupon's customer service and am trying to get my money back.
