Anyone gotten new RV tires in Boise, ID?

When I got there and got the paper work done I told them I would wait in the MH they told me they were busy and would get to me as soon as possible. They went back and changed 3 tires on a semi truck that took 1 1/2 hrs. and this guy came after I had my paper work completed, while I sat and waited. First I had them put in the balance beads and I had to tell them to pull the old lead tire weights off. Second they only had 4" long valve stems so they put 2 long stems on the rear dully and reused 4 of my shorter stems but installed new gaskets on them now I cant rotate the tires but they charged me for 6 new stems. Third I had them install valve stem extensions and it took 1 1/2 hrs to drill 1 simulator. After talking to the manager and getting no where he only gave me excuses it took them 5 hrs and 45 min. for what they told me would take 3 hrs. I wrote a letter to their corporate office 3 weeks ago and have not heard back from them.
