National Multi List Service, Jim Jones, Jim Brand, Carla Do not trust this company Denver Colorado

On May 20th, 2013 I was contacted by Santanya of National Multi List telling me they were the internets largest  A website for used "For sale by owner" RVs.  They worked on a one-time fee until sold.  I agreed to purchase a premuim plan for $299.00 for a five month period.  They sent me a contract letter together with a refund coupon.  The coupon stated that if the unit fails to sell within 150 days from the date of purchase, the amount of $299.00 would be refunded in full.  The letter also stated that they would continue to advertise my unit until it sells.  After 150 days my unit had not sold and I sent the refund coupon back to the attention of a Mr. Jim Brand.  After repeated calls, I spoke to Carla who confirmed they had received the letter and who said I would receive a check by December 7, 2013.  No check has been received and repeated calls to several different listed numbers have gone unanswered.  A complaint to the Better Business Bureau of Denver on November 19, 2013 also failed to get any response from National Multi List.  It appears this is truly a scam operation.  Do not waste your money!
