Bought a massage thu app. When I called to set up time, the therapist was booking TWO MONTHS out. Just before my appointment, app claimed that I already had my appointment. (?!) Groupon refused to refund my money and would only give me a credit, but offers few goods or services near where I live to spend it. Now it just recategorized my credit as a "refund" without ever being able to identify any date they returned the credit to me. Dont use this train wreck of an app. Groupon steals your money.
