Bad dealership experience
 

So I just recently bought a 2015 Coopers S 2dr hatchback. On all the 3rd party vendor sights like Cars.com, cargurus, autopilot etc, it was listed to have satelite radio. I bought the car and it looks great and runs great. I finally get some time with it and guess what. No satelite radio. It has the hardware to support it but it hasn't been activated by Mini. Problem is, I bought it from a Subaru dealer. The add is still up on all the other websites that states that it has that radio. How do yall propose I go about dealing with getting this dealership to pay for my upgrade? Or do you know of a way I can upgrade it myself? Thanks for hearing me out
