Kalo Services Inc., Overcharged Air Conditioning

I did not have a very good experience with Kalos Services Inc. They constantly tried to overcharge me and find reasons to charge me more. They checked my unit and at first the problem was just the refrigerant, then charged me $100 more to check for a leak. From there it was one thing after another. They charged me nearly $300 just to patch on the leak and then discovered another issue because somehow my bill came out to a grand.
