Amazon.com Amazon False Advertising Regarding Seller Aneheim, California Internet

I ordered 3 CNC machine parts from Amazon.com.  The description on the Amazon.com website stated "Sold From and Ships From Amazon".  This is the preferred way I buy from Amazon, in case of damaged goods, Amazon will pay for return shipping.  After I completed my order, the parts were shipped directly from the part vendor, VBX Bearings in Anaheim, CA. I received the order and one of the three parts was warped.  This is where the issue comes into play.  The vendors information states they don't cover return shipping charges, and there is no reorder/replacement option.  So I have to pay for a heavy, oversized package to return a defective product that was shipped by the vendor.     I contacted the vendor, VBX Bearings, and Amazon.  The vendor failed to reply and Amazon.com lists no Customer Service phone number.  Amazon's website seems to only allow electronic filing of the complaint and redirects my refund request to the vendor directly.  This is, in my opinion, tantemount to bait and switch.  The whole reason people spend a certain amount on Amazon when ordering is to receive free shipping and guaranteed no hassle returns.  Amazon's ommission of a direct customer service phone number is also telling.  I have bought from Amazon for at least a decade or more, but I refuse to purchase anything from them or VBX Bearings again.  Amazon's prices are quickly outpacing the retail local market these days as well, as without any meaningful customer service, and especially with changing the vendor details , After the sale is complete, it is likely other people will folow suit and avoid Amazon.  Using a person's credit card for an interstate transaction, then changing the details of that transaction after the customer accepts, is illegal.
