Rosland Capital charged excessively high "comission" rates in their exchange for my gold. My calculations came out to a 24% fee for the exchange or "trade" transaction. They took my gold bars at my request, and gav Internet

Rosland capital's rep, Chase Greenich is a slick operator, using "good cop, bad cop," techniques in regard to his "administrators, who wanted to give me less value, and he had to fight for me,and was on my side."  I've bought gold for years now, but never had to pay such high "sales expenses." 

I felt they were a fair company because they advertised on Fox News network, also was a fan of G. Gordon Liddy, and his character in taking the "rap" for a previous government boondoggle.  They're not!  All I'm asking for is fair value...a 7 to 10% fee would be acceptible, but not 24%!  I couldn't get a straight answer from Chase, but did they charge me 12% for the sale of my gold, and 12% for selling me their gold?  The amount was substantial to me.  If the value of my gold was $500,000...24% would amount to $120,000 I'd have been charged.  Is this a normal trade fee?
