Feedback on resolving problem takes forever

<p>The Chevrolet vehicles features that are advertised on the website are not in the vehicles after one buys them. I have consulted with GM to try to rectify the problem, and have not received a response for months. I have proof of the information published on their website, yet these features are not in my vehicle. I have been told the problem is being escalated to different departments, but nothing has been happening for months. I am not the only customer that has experienced the problem of features not being in the vehicle as indicated on the website. They have not been concerned about me rating them does for these issues in the surveys and have ignored the issue that I indicated that I will take this now further. Publicity does not seem to be a problem to them. They have not responded to my requests in a manner to solve the problem.</p>
