I ordered a part on the 7th hadn't heard a thing by the 17th. Filed a complaint on the website and still heard nothing. Filed a second complaint and got no response. The item showed up on the 21st with a shipping date of the 17th, so they didn't ship it until I complained. This is all fine I understand that people make mistakes. My problem is the complete lack of communication. A simple response to my complaint of "sorry we forgot to ship it, it's on its way," is all it would take for me to be a return customer. Since they don't have the common courtesy to reply and don't communicate shipping information at all I will not use them again.
