Three heating and cooling techs, and my A/C machine is still broken.

I knew there was something wrong with the air conditioner machine even before I had the heating and cooling professional do the inspection, however he told me he had to order the parts, which I was perfectly fine with. He said he would order the A/C parts, and the next week he would come back and install them. When he installed the new parts, the air conditioner still didn’t work. He seemed surprised the A/C was still broken, He told me he was going to have a colleague come look at the air conditioner unit, however I asked if I was going to need to pay extra, although he said it would all be part of the original repair call, and the second heating and cooling professional arrived and he said I needed a fan motor. They ordered the fan motor and returned the next day to install it. The fan motor worked, however I still wasn’t getting a good air conditioner. They both looked lost and wanted to call another heating and cooling professional. I told them if the air conditioner wasn’t repaired this time. I was going to hire another heating and cooling contractor and I would contact the owner of their heating and cooling contractor. The third heating and cooling professional arrived and hit the reset switch. Within seconds the air conditioner machine was running and there was cool air coming from the air vent. When the first heating and cooling professional turned off the power, he forgot to hit the reset switch. I wasn’t excited when they tried to make me pay for three heating and cooling professionals and all those parts, when the reset switch hadn’t been touched.
