Hi Wen,
I'm sorry that you are not happy with the repair work and I wish you would have contacted us directly to discuss. I reviewed the notes and we replaced your starter which has nothing to do with the air conditioning system. We have ASE-certified a/c techs on staff and would be happy to ascertain the reason why your a/c system is not working; unfortunately, the repairs we did are not related to the a/c system so you would likely need a/c components replaced to get your a/c working the way you'd like.
