nikki Strong-Boag review about company speedy plumbing and heating

I am very unhappy with this company. I called them to replace a cartridge in a Kohler faucet for the kitchen. They arrived and demonstrated little or no competence; after they wrestled w/ it for a time, it seemed to stop leaking but an hour later it was spewing water. They charged $250.95. Two days later they returned after I bought a new Moen Faucet and charged a further $156.45 for 1/2 hour's work. I queried the charge but they insisted they bore no responsibility. Since they clearly did not know what they were doing in the first visit, I should not have had to pay a further 'service' call. Not competent … and dishonest I think.
