Complaint Review: Groupon

I purchased a "certified refurbished" Dyson V8 from Groupon.  ($400-All sales Final)  Although the vacuum does function, the Carpet attachment was badly scratched and should have never been re-packaged for sale to another Customer.  When I contacted Dyson the next day about the issue, they explained that they would not replace it without charging me.

I attempted to leave this feedback on the Groupon website as a 2* review, but Groupon censored my review and rejected it, twice.

I emailed Groupon Customer Support and 2 days later recieved a canned reply with instructrions on how to leave feedback (as if they didn't even read my complaint)

I am stuck with this vacuum.  It was supposed to be a Christmas gift.
