Worst customer service I have ever experienced!!! ...

Worst customer service I have ever experienced!!! They sent the wrong part. I called and, they told me to return it. I paid an additional 70 dollars for return shipping. Only to have them deny the refund. Claiming the part was "greasy" and therefore used. The girl I talked to (Christine) was extremely rude. She kept saying I implied the part was used. Then. Even going as far as calling me a liar when I stated, I never said any such thing. I am now out over 400 dollars and will be filing a complaint with the BBB, as well as a paypal dispute. Never again..
