Terrible customer service. My order was supposed to be delivered today, and it wasn't.
Usps tracking hasn't been updated since RockAuto told me it was shipped. According to the post office, they were never given the package, but yet RockAuto says it's in transit.
After contacting them about the problem, I was told to wait another week, and then go to their website and fill out a complaint form.
I sent them another email demanding a replacement, and they never responded, but they gladly took my hard earned money.
I will never do business with them again.
