Why are my resale tickets not available???

I posted my resale tickets on Friday and today is Wednesday. My tickets I am selling still are not showing as available for purchase. The show is in 3 days. WHAT THE HELL? The only agent I have been able to speak to says they only list 1 option at a time and it's first post, first shown. Is this correct? Then I get the instant offers to sell at a value below what I paid face value excluding the service fees
