Refused to explain different feautures

I went onto cartrack website today hoping to get info on different systems they can offer. I requested to be called back with more details. During the conversation I asked the sales guy to explain the different options and features that cartrack can offer clients. The guy refused saying \I can not explain all the units we have, we just have a lot\". I got puzzled and irritated as to why did he call me in the first place if he can not give me more info so that i can make a choice on which tracking system best suit my lifestyle and security needs. Instead he wants to know the type of car I drive then forces me to make a choice for me. I find that very unfair as I can be driving a low risk vehicle but in need of high security based on my lifestyle conditions. I can not have someone force me to take the unit he prefers when he doesnt even know my budget. His sales skills needs to improve because he ended up hanging the phone on me without assisting me. That simply means he doesn't really care about clients. its either we listen to him or he hangs up. Very disappointing client relation..."
