I bought a Dyson on Groupon. Groupon told me to go through the warranty I got with it. I only had 14 days to return. I called Dyson and they sent me a part. That did not work. Called Dyson again told me to take it in to a shop that they paid for, vacuum still did not work. Called Dyson again and had it shipped to their techs in Washington, got it back and it still did not work. Told Groupon that their 14 day return policy was garbage. It took longer than 14 days to get the first part. And asked for refund. Groupon again told me to contact Dyson. Asked Groupon to speak to one of their supervisor 3 days ago, still have not heard back. Received an email saying my 14 days was up... no kidding. Very unhappy with Groupon and Dyson... WILL NOT BUY AGAIN!
