Best Reverse Osmosis System Repair in Phoenix AZ

My home warranty company sent me a plumber from Laszlos and I was beyond disbelief on the level of unprofessionalism and rudeness I received from the owner at Laszlos. He tried up charging me a ridiculous amount for a water heater my warranty company covered. When I asked the owner the model and brand of the water heater his company would be installing he said "You don't need to know that, the only thing you need to know is the extras I am charging you and what you are paying out of pocket" excuse me sir, this is my home and of course I need to know what is being installed in my home. I ended up going with someone else and paying out of pocket just so I didn't give him the business. Also the plumber the owner sent was also pretty rude as well. As consumers we should not allow companies to treat us poorly and still give them business just to save money. If you look through my reviews you will see the plumber I ended up using and I ended up giving 5 stars to. Avoid yourself some headache and if your warranty company wants to send Laszlos tell them to send someone else.
