Auto Parts Warehouse won't pay for shipping back wrong order; rude customer service; Carson California

After the Better Business Bureau complaint failed to move the resolution forward, I contacted the California attorney general's office online. They have an easy form to fill out, then follow up by both email and paper. Within 24 hours of APW receiving my complaint from the Attorney General, I received a notification that the refund had been transferred to me!
I also received a form letter from the company apologizing for the inconvenience and offering me a $20 discount on my next order with APW. I'm not sure why they think that I would ever use them again.
In summary, beware. If you have a problem such as I did, (and it looks as if this behavior is pretty common) I suggest going directly to the state AG's office to file the complaint, then put your story online at this site. Let's keep e-retailers honest.

Since writing the above report I filed a complaint with the Better Business Bureau in California. I sent the parts back ($66.31 shipping costs on UPS) on 6/3/08, tracked the items as they arrived at their warehouse on 6/10/08, and received a refund for the cost of the struts, but NOT the shipping costs, soon thereafter.
On 6/24/08 I received notification of a response to the BBB complaint which said I could have the shipping cost IF I provided the tracking number of the shipment. I had not kept the receipt once I had the refund, so I called them (many times) but they have stonewalled. Their live help line is also not helpful. I have asked several times to speak with a supervisor, but have been told each time that one was not available, but I would "get a call back as soon as one comes in today." Hasn't happened yet.
I then filed a report with the California Attorney General's office, which is remarkably easy to do, and they've been great about communicating back to me. At this point I'm waiting to see what response they can get from APW. I'll continue to update.

Have finally reached the end of trying to communicate with this company.
I'm including my last conversation with them (through their live help line on 5/30/08) as evidence of the type of response I have gotten from them for the past three weeks.
I'm sending the same to the Better Business Bureau, and also sending back the struts in order to recover the remainder of my money.
So it goes.

hi
2:15:41 PM Richard
This is, I believe, the third time I have had to ask for a rma# for RL3375145. Can you make sure I get one?
2:16:31 PM Bret
May I know the exact reason for the return?
2:16:45 PM Richard
You sent me the wrong part.
2:17:45 PM Bret
RMA # - 5208-901
2:18:17 PM Richard
Thanks! Now can you send me a voucher for the return shipping?
2:21:50 PM Bret
Return address:
17150 South Margay Avenue
Carson, CA 90746
2:22:17 PM Bret
Please mention the RMA number and order number on the package.
2:23:33 PM Richard
Thanks, Bret, for the return address, but these are 4 struts that weigh about 50 pounds. Shipping is likely to be considerable. I have them because APW sent them to me mistakenly. Don't you pay for return shipping in this situation?
2:24:16 PM Bret
I am sorry, We do not.
2:24:53 PM Richard
Interesting. So to get back the 314 dollars of mine that you have taken, I have to pay around $50 in shipping charges?
2:25:16 PM Bret
Yes.
2:26:25 PM Richard
I'll have to do that then. Please read my post on www.ripoffreport.com, where I will put this conversation, and expect to hear from the better business bureau of California when I send it to them as well.
