Abra Cadabra Plumbing Heating Sewer & Drain Cleaning

The more time goes by, the madder I get.
I interviewed several companies to have AC installed in our 30 yo home. The guy really sold me on his expertise. But when the day came: They cut open entire walls to run 2 air pipes. One guy was cutting drywall with a bare razor blade (no handle), one large section wall was an ‘oops’. They were messy & unprepared. When they started to run the next air pipes — I stepped in to show them they could do this without taking out the entire wall only cutting a small hole near the floor. We knew they were going to cut the drywall & not repair it — but OMG. They just didn’t care.
The expert guy was on the phone the entire time & only worked when the inspectors showed up. The drain pipes were run uphill — so needless to say by the 2^nd summer it flooded my kitchen. Someone of them told me that «service contracts» are their bread & butter.
After I got a service contract from a reputable company they were forced to change the drain pipe (left a whole in the side of the house). Said they can’t change the emergency drain without reinstalling the air handler! Verbally guaranteed they would if it failed again. We have since been informed that the air handler is too small for our home.
If we’d gotten a service contract with them they would have a little gold-​mine because something would always be wrong. Like magic.
Prior to the flooding I also hired them to do some general plumbing:
Upstairs bath faucet & drain replacement & broken pipe: I put out a large board specifically to put on the washer & dryer directly under the bath drain, they ignored it. My washer & dryer are dented & scratched from them climbing on it to get to the overhead drain. The plumber’s truck looked like a bomb went off in it & he tells me he’s going to reuse the very old gasket cause he can’t find a new one in the truck! I took the old gasket from him. It hasn’t failed — yet. They cut a hole to accommodate a plastic access door which they provided. But cut a huge access hole in the ceiling — still there.
Downstairs Shower head & handle replacement: They burned the fiberglass shower wall. They removed the water-​saver feature & the force of that shower hurts so nobody wants to use it. The new faucet drips constantly.
Replace gas line to outdoor grill: Didn’t run it from or put it where I asked them to, glaring yellow eye-​sore. Hired a different plumber to change the connector to 90 degrees as they had it sticking a foot straight up & rain was entering the latch.
I called them with every mishap. The owner yelled at me. Called me a b***h, accused me of trying to get free work. I suppose when I post this they’ll hunt me down.
