I have been ordering parts through Rock Auto for the last few years. haven't had many issues with them. The prices are fair and the parts are quality, however on 4/22/2016 I ordered the wrong Alternator. I took it out of the box and saw the plug was wrong. I set up the return and sent it back to them. Weeks of waiting on my refund, I get on their site and see that the part is non refundable.
I call the customer service to find out why and I am informed that the warehouse says there are marks on the tabs showing that it was installed. No the part was not installed. I took it out of the box and put it back in. That is it. So over a hundred dollars of my money they decide to keep. I am informed that they can give me the measly 35 dollars for the core. Right, on a refurbished Alternator that they will put back on their site and sale it to someone else. Never knew I needed to take pictures of parts I receive.
Very poor way of doing business. Any local parts store I've ever been to have ever not refunded money. The customer service is Crap. I WILL NEVER DO BUSINESS WITH THEM AGAIN!!!!!!!!!!!!!
