Best Pendant Light Repair in Phoenix AZ

We had George Brazil out yesterday to replace a bad water heater that they installed a couple of years ago that was still under warranty.  They tried to charge us almost $600 to replace it even though it was fully under warranty and it was the 2nd time in 2 years that we had to call them out for issues with this same water heater.  They did drop their fee to $400, which to me is $400 too much for a bad water heater that they installed.

The really bad part is that after they left, we noticed that the master bath toilet now makes a REALLY loud vibrating noise after you flush it.  We've been told that this is because they injected air into the pipes.  When we called George Brazil back, they said that it wasn't their fault and that they would charge us to come out and fix it.  This is the most disreputable plumber I have ever dealt with.  I will never use them again.
