American Freight - Penn Hills Location American Freiight sold the sofa we purchased in full the same day after we left. Penn Hills Pennsylvania

We went the store, picked out a sofa and purchased it in full yesterday.  We decided to rent a U-Haul and pick up the sofa the next day to save $30 from the delivery cost.  The day we purchased the sofa we asked if it was possible to purchase the floor model for a small discount.  The salesperson said they can't sell it until the inventory in the back was sold and that they have one wrapped in plastic brand new for us.  Today when we get there to pick up the sofa they told us the computer inventory was wrong and they sold the floor model after we left.  The manager, Brian, also said that the sofa was discontinued.  He then told us that he would refund the money for the sofa and there's nothing to be done about the $50 for renting the U-Haul.  There was not sympathy or effort to rectify the situation.  In my experiences, when someone purchases something in full, the store has the responsibility to mark it as sold.  It's pretty much a contract.  This situation was unfair and I hope that it doesn't happen to anyone else.  I will continue to inform people about how we were treated at this Penn Hills American Freight by Brian the manager and his sales team.
