Universal Hyundai Sold me a car with a bad hub bearing and has ignored all my calls trying to resolve the issue. Orlando Florida

I was in the market to purchase a car in February, I contacted Universal Hyundai and spoke with a sale representative. The were friendly enough calling me repeatedly assuring that I was coming to see the cars. I finally went in to see a car they had advertized and afetr being told that the car I wanted was no longer available was ahown an other vehicle which was "newer' and a better deal, I was at the dealer for about 2 hrs and got upset with all the stalling and being shuffled between salesmen so I left. The called me again and I agreed to come back in. I eventually purchased the car they had shown me after again being shuffled around for about 3 hrs, it was about 10 pm after having worked from 7 am to 6 pm and then driving in rush hour traffic for about 45mins to get to the dealership. I had my grand children with me an just wanted the whole ordeal over. Even through all the pain, I felt happy with the car as it was nice a decent deal  but when I finally was able to leave with the car (it still needed to be finished being detailed and cleaned and have the tags put on) I felt good sitting in the car. as I left the dealership and came on to the main road, I hear a whinning sound coming from under the car but it wasnt very loud and since the road was wet I thought maybe it was the tires on the pavement. The next day I again noticed the noise and began to try to ascertain where it was coming from. First I thought it was the tire design but eventually I realized it was coming from the left front wheel bearing. I called one of the sales people I had dealt with and informed him of the problem and was told he would inform the main salesman in charge and that they would get back to me. after a few days I attempted to contact the main guy myself with no luck. I then call the first guy again and again was told he would pass along the information, and that he was just a little guy and couldnt do anything for me, that he waould have to get the salesman in charge. I called everyday for several weeks and have not been able to get anyone to talk to me at all. I even had the coutesy desk page the person I needed and after waiting on the phone flr a while the line went dead. Before they sold me the cr the were falling over themselves to talk to me but now I cant get anyone to call me for anything.  I will never buy a car from these people again and I will tell everyone I know not to trust them, I plan to post all my trouble to my facebook and have all my friends share the incident as possible.
