Complaint Review: USARims

I bought beautiful new rims with new Pirelli snow and ice tires to be pre mounted and balanced for my 2009 Porsche Cayenne Turbo S from USARim in November 2012.  I specifically asked that TPMS (tire pressure system) be installed in each tire.  It is now mid December and after delivering to my Porsche dealer to have them professionally installed, I am being told they do not have the necessary TPMS in the tires.  It will now cost me $400 to have the tires broken down and the TPMS installed, re-assembeled and balanced...which is what I initially contracted USARim to do.  I called Frank at USARim who put me on the phone with Ian. I told Ian that I had done the deal with Justin.  Ian told me that was impossible since Justin had not worked at USARim since April of this year, and my transaction was in November. I did not make this up..and I also remember someone subsequently referencing Justin as the owner's son. Ian then went through a canned spiel about having told me that the TPMS s/b installed and that I agreed to not have them installed. I never agreed to that, but do remember asking if the TPMS were the proper frequency for the Porsche vehicle I was having them installed upon.  I was told not to worry, that they knew what they were doing. He also stated that I signed off on that statement which I put back to him in a form which he sent.  This form is in my work computer which I will check once I get back to the office tomorrow.  This is not the end of this....
