Terrible customer service. Made a big order for a project of mine that had strict time constraints. 2 days later I receive and email indicating that one of the items is out of stock. They offered no solutions other than to wait 4 months until item is back in stock. I propose another item in exchange, but only way of getting it in time is with very expensive next day shipping. They, of course, refuse to assume shipping charge when in reality is their mistake for not mentioning item is out of stock when charging my credit card. When talking on the phone, customer service woman was extremely rude because my accent wouldn't let her understand the invoice number, treated me like a dumb 5-year old. What a waste of time.
