My heater went out in my house. Entire line was dead. I tracked it down the fusebox and called a HVAC guy to come change the fuse box.

I should also mention there is fusebox disconnect that I had assumed was my furnace but I am not an AC guy. 

The HVAC guy comes in and tests the disconnect (believes it goes to my electric furnace) and there is power from the disconnect but there is no power to the furnace. He claims the fusebox is fine and that I shouldnt fix what isnt broken.

He cuts the wire from the aforementioned disconnect and runs to the furnace with a new wire directly to it.

He leaves after I pay him 300 dollars for this.

Well come to find out that disconnect was my fucking stove. I no longer have an oven working.

My friend comes by the next day and starts finding all sorts of things wrong with his installation. 

I end up paying someone else to install a breaker box in place of the old fuse box and now everything works again like it should.

AITA for wanting my money back?
