I had Worthington Air come to fix my air condition...

I had Worthington Air come to fix my air conditioner. It was $85 service fee. They came out once and said the unit was frozen so they would need to wait until it thawed to come out again. That's fine. They didn't charge me for the second visit, but I did have to take off work twice. The next visit they said it needed new refrigerant. I asked if it could possibly leaking, he said he would check and let me know. He said it wasn't leaking so it should be fixed. A month later it is broken again. I suspect it is leaking. I called Worthington to ask if they would forgo the $85 visit fee to look at it again and they said no. I contacted another company. Fool me once, shame on me. Fool me twice, shame on you. For shame Worthington Air!
