Rockauto Refused to exchange or refund a wrong auto part Madison Wi

Ordered front parking brake cable for my 1997 Chevy Camaro z28. My original cable got rusted and fell apart. There were only two options available on Rockauto, both with the same length. I assumed the cables were identical, but differ in quality. I ordered a pro version. When the cable arrived, it looked a little different from my oem, but many aftermarket parts from Rockauto  looked a little different before, so I proceed with installation. It turned out what the replacement cable is 3” longer than supposed to be. The slack is not adjustable.

I search online and all auto parts stores sell the same length for my model year. But the part didn’t fit. Fortunately I checked the earlier model years and a cable from 1995 camaro on Rockauto looks and fits my car perfectly. I contacted Rockauto asking to replace the cable. Rockauto dismissed my claim and refused any refunds since the part was installed and they have no other cable available. Even though I pointed them what they list a wrong item under my car category, but have a correct one for another model year. I was  a loyal Rockauto customer since 2008. Anyway,  they stop responding to my email. I called their Corporate office several time, left messages with no reply. Needless to say, I will stop shopping at this company because of the level of customer service they provide.
