I was sent the wrong item and need to return it

Contact the vice president of company or file a suit

MOST EVERYTHING YOU BUY ANYMORE HAS PAPER VWORK THAT TELLS U HOW THE BEST WAY TO SENT BACK A ITEM.

wrong site were not amazon

One of two things... either you addressed the package wrong, or there is no address that exist

.most likely you addressed the package wrong...if it was going back to a business..you need an actual brick and mortar address.. not a P.O. box...

contact the seller by phone or e-mail
explain the problems and request an authority to return
if you used paypal or other secure method of payment and if the seller doesn't respond make a complaint to them

Has Nothing to do with your porblem

Take it back to the place where you bought it or call the on-line parts distributor where you purchased it to discuss your issue. It's important to have serial numbers and model numbers handy when ordering parts.
