Another Scam on E Bay

I bought a pair of Polk fx 1000 speakers from a company in California off of EBay, they were advertised as being new with a 5 year waranty, upon receiving them, they were obviously not new, also with a broken dipole switch and stripped threads on the bidding post, I called Polk and they said that the seller was not a authorized dealer and that there was no waranty, luckily my credit card company has put a hold on the charge, after that , the conpany contacted me and offered to replace speakers if I filed a claim for shipping damage against ups, I told them that the speakers were not damaged by ups, and would not participate in fraud against ups, at that point they hung up on me, this company has many ads for polk speakers on ebay, before you buy ask for sereial numbers and check with polk !
