I had installed the Groupon app on my phone. By doing this, I accidentally purchased a $200 cleaning service. By the time I noticed the purchase, it was too late to cancel. I informed Groupon and explained the issue. They admitted there were other customers who had installed the app and issues as well. Even after admitting it was their issue, they claimed there was nothing they could do.
I gave up and tried to schedule the cleaning. It took 2 weeks to get them to return my call, postponed the cleaning twice, and cancelled 30 minutes before they were to arrive. Then the owner hung up on me when I called back. Dont ever use Groupon! Biggest scam ever!
