Narrative:

This flight was the result of a diversion of the original flight to ZZZ. After receiving clearance from approach for the visual into ZZZ was informed by the dispatcher via ACARS that the airport ops was reporting a NOTAM of a ficon (field conditions) of ice (tower is closed at this point in time airport is uncontrolled). Upon receiving this information myself along with the first officer and dispatcher concluded that a diversion was the best course of action at that point in time until we could get some better information on the conditions at ZZZ airport. Diversion went as planned no issues. Once parked and at the gate; I called the dispatcher to see if we couldn't figure out a course of action. We discussed a couple of things as he was in direct contact with the ZZZ operations. Eventually we were informed that the landing runway had been treated and the NOTAM of 1/1/1 had been removed and the airport was reporting a ficon of 5/5/5 braking action good. We decided that based upon this information there was no reason that we could not proceed to ZZZ. We re boarded the airplane and proceeded on our way to ZZZ.the departure; enroute flight and approach were uneventful. After landing is when I noticed that we as a crew and the dispatcher had been misinformed. The runway was covered with ice and the braking action was very poor almost nil in some areas. I was able to eventually bring the airplane to a complete stop using brakes; and thrust reversers. We were able to gingerly taxi the airplane off of the landing runway onto the intersecting runway where we further started to slide about and ability to maintain aircraft control was almost impossible. We brought the aircraft to a complete stop again on the runway in a last effort to further taxi to the terminal we tried to turn north onto a taxiway and began to slide again uncontrollably eventually leading the aircraft almost doing a 180 with the tail facing north. We were able to get the airplane to stop on the taxiway now partially on the taxiway facing south with the airplane's nose touching runway. After this we decided that further trying to taxi would not be a safe option so we shut down the engines and contacted operations as to our situation. Stranded on our own for roughly an hour and a half we tried to come up with a plan while talking to the airport operations to which were pretty much left stranded on our own. The only help we received was a lone fireman that was able to help us deplane the passengers 2 to 3 at a time while making runs from the airplane to the terminal.late night; we were misinformed to the true state of the airport in ZZZ the airport was pretty much one huge sheet of ice. Airport ops was no help as the airplane was unable to taxi as well as stuck on a taxiway about half a mile from the airport terminal. Overall this is a huge learning experience on so many levels. I guess what bothers me the most is that in this situation there was a feeling of helplessness and frustration not with the company or the crew; but with the ZZZ facility and the information given to us prior to flying there and once on the ground. Honestly it's going to be hard for me to trust this station or anything associated with it from now on. All of this could have been avoided if people were honest.
