This is the 7th call I have had from them. This robo-caller will not respond when you answer, very frustrating. Every time before when I would call the number back would just get a busy signal. This time It took a few times but got through to an arrogant sales guy for construction materials. This fellow had the nerve to tell me that they don't call and not respond when you answer " that didn't happen" very obnoxious place or perhaps this guy just has the wrong job.
