Groupon may have good deals, but its not worth the hassle when there is a problem. Customer service is most clearly outsourced outside the U.S. and not readily available. Good luck trying to find a phone number to call. My account was hacked and 3 purchases made all at once. The tracking information was suspicious (the items were shipped before the fraudulent purchases were made). When I contacted them by Live Chat and email, their first response was, "Are you sure someone else you know didn't make these purchases on your account, from an international location?" Uhhh no. What I find most disturbing is that I hadn't signed onto Groupon in over 2 years and yet my credit card information was still stored on my account without requiring some type of security measure or verification of CVV code. I had also moved so you would think it would require the entire credit card information to be reentered like most reputable websites. For these reasons, I would advise consumers to not use Groupon - your credit card is at risk. I was able to catch the purchases before they posted, but I still had to cancel my credit card, what a headache. And beyond frustrating to feel like you are being blamed by Groupon. Research them - thousands of people have had this same problem and Groupon won't admit any wrongdoing when clearing they have a security issue.
