Worst phone service ever... I am buying a 10 000$ lamp and i've been trying to talk with someone to know where is my order for a week now and got no answer. Jim the Sales Manager said he would call me back and did not. Every time i'm trying to call the Web sales dep. I end up on their voice mail. First and last time with vistek.
