Bought a groupon good for 4 visits at this location. Have since redeemed 3 out of 4 and today they are saying they won't let me use the last one per the instruction of their boss. They said it wasn't good for their location and won't accept them anymore even though my groupon clearly states the San Tan mall location. Pinned right in the map too! If it's been a problem, why don't they have groupon delete the deal?? They clearly have no customer service skills.
