No response from Autotrader

I placed an ad on the autotrader website and accidentally selected the wrong model car as my model was not showing up on the drop down list, so I assumed I could select the closest one and then call/email them to fix it.<br> <br> It's been 2 weeks and I have tried calling multiple times and sent numerous emails and absolutely no response.<br> <br> This is absolutely unacceptable and would like to warn others to not waste their time with the [URL Removed] website.
