"I purchased some network interface cards for servers and they emailed for information about the credit card I didn't have (department card, set up by another dept, probably one of two possible business offices). When I called, the sales person was rude, repeatedly interrupting me to restate points I already fully understood. I had to resort to raising my voice in several escalating steps to the point of shouting to finish my point. Not good.
Also not good: they shipped the cards without the "included" low profile brackets and have ignored my emails on the matter."
