Would recommend to not offer a Groupon if you can't answer your phone or return a bloody text message. 3 attempts and nothing. Even went in there to make an appointment. Was given a card and told to call for an appointment. Sure, that worked,. This was counterproductive and a colossal waste of time!
Perhaps you can extend some professionalism and honor your offer. Fortunately, Groupon credited my account. Buyer beware!
