CarAcquire Provided with false promises from start. No response to emails regarding refund. Colorado Springs, Colorado , Internet

I was contacted by their representative to see if I would list my vehicle through them. He stated that they had people waiting for this type of vehicle and that upon signing up and paying the fees, they would direct them my way. I was told that people would be calling for appointments on the weekend following sign up and also there would be more people calling in the forst 2-3 days of the following week. I had zero calls after 10 days, but my Kijiji ad was generating lots of interest. I took an offer after 12 days, and still no callers via CarAcquire. I tried on numerous occasions to email them and no response.  My experience is that if these people call you, just hang up.  They are mis-leading in their promises and unresponsive to concerns after.  I have already listed a complaint with BBB in Colorado (which CarAcquire didn't respond to), and will now proceed with complaints to BBB, and appropriate law enforcement and regulatory agencies in Canada.  People like this should be ashamed of themselves, but I guess that is expecting too much given their total lack of ethics.
