Customer Service Issue

The customer service representative who is also the manager, refuse to do business with me. Apparently he doesn't like to answer questions regarding the product he is selling. As a consumer you want find out the best deal, questions about the product. The internet enable the consumer to shop the best deal and if another company have the same product but sold at different price, you would want to understand why the price is different. The customer service rep/manager name is David ext. 207, appears to lack customer service skills. If anyone is trying to buy from this company make sure you do not deal with David, he is very rude, and appears to not care about the consumers.
