Sun Art Designs Inc

I have been trying to do business with this company for 6 weeks. Had questions about pricing, min. order, application instructions. Sent them a list of stock transfers, because you can't just put them in shopping cart and buy. No reply, 2nd request answered by a vice president of marketing, said someone would get back to me following Monday, nothing. Finally spoke to rep, I had to send list to him again, he said he would check stock availability and cost, would get back to me right away, still nothing. What is up with this company, if I ran my company they way they do, I would have been out of business long ago.
