eComfortusa.com Horrible company to deal with, Internet

Wow, what a lame company.  They are very good at getting back to you when you want to place an order, but once the order is placed you may as well forget ever hearing back from them.   I ordered a fairly expensive ($1500) heat exchange ventilator from them.  They immediately charged my card and two days later emailed me that the item had been shipped.   However, they will not provide a tracking number.   Of course, two weeks later, still no merchandise.   In an effort to find out where this is at or what is happening I have been trying to get them to simply give me the tracking number.  I have been emailing them for over a week.  No response.  I have been calling them 2-3 times a day for over a week.  Not only is there no response, but all I can get is an answering machine.   The last couple days I can't even get onto their website.   Either their server is down or they have moved on and are now running scams somewhere else.  After numerous attempts to contact them,  I finally had to call my credit card company and put this charge in dispute.  It would seem that there is enough business on the internet that a company like this would be more concerned with the long run, but these guys seem pretty fly by night.
