Rockauto does not care about customer service at all.
I ordered 2 headlights and one air filter and payed for shipping as well after one week I received 2 headlights in very bad condition due to the poor factory assembly and I requested the return label) from Rockauto and returned the items to them.
Here are the issues:

A: I returned All 3 items to Rock Auto as they sent me pretty much bunch of garbage but their customer service saying the have received only 2 headlights from the retuned package! and they did not received the 3rd item which was being packed in the same box!

B: They have issued me less than %40 of what I payed for!

C: they charged me full payment again for the return shipping! ( %70 of my money went for 2 times shipping and returning the items just because they sold some garbage which I gave it back to them.

D: Now I sent several emails to their customer service but no response!

I never buy anything again from Rockauto and will never recommend this company to anyone for any kinds of service.
