My a/c was worked on at Puente Hills Toyota, and it all of a sudden stopped working, can should I take it back there?

My car went wrong the painting I spoke to them in July and August they told me that I had it so they can review it to see and since then I can not talk to Roberto gamboa with him I made the deal

Yes, you should. If you bring it to somewhere else, you void their liability. Make them liable for their work.

Of course, take it back asap, to assure some more serious issue has not occurred.

Yes...
