Capital RV Sales It's a Ripoff. Don't Trust Them Internet

This company contacted me about selling my motorhome. The salesperson was very nice but very aggressive. They promised all kinds of things, including handling the sale of my motorhome and advertising on multiple websites, for $299.  They encouraged me to list it for far above NADA value.  I supplied the description and the pictures.

They actually charged my account for $499, not the $299 they told me it would be.  I have contacted the sales manager several times about this error.  He has assured me each time that he will correct the error, but he has not.  He always acts surprised that the error hasn't been corrected.  In three attempts?

I have Googled my motorhome, and I don't get any hits.  The only place I see it advertised is on their site, and I have a hard time finding it there.  Even $299 for this service is ridiculous!  What a ripoff!
