I never received my entire order from Blue Earth Enterprises, the company that Amazon went through for the chains.  The invoice even recognizes that one of the chains was never sent.  Apparently, they don't care.  I emailed customer support on their website after waiting a few weeks to see if they would sentd me the chain late.  It was near the Holidays and thought maybe they were out of stock.  No response.  I am not sure what recourse to take, and since the chain was inexpensive, I probably won't do anything else other than email the company one more time.  Otherwise, I have been happy with the chains.
