Best Services Whirlpool in Gilbert AZ

We are remodeling our bathrooms and needed a plumber to run the new shower systems. Our contractor had Wyman come install one. They gave a quote without asking us, the homeowner, what type of system we purchased. Needless to say, they missed installing the handheld shower valve. I am not completely sure how this could happen since the instructions are very clear and specific. They scheduled another day to come back and complete the job. They are charging us by the hour, fine. I was told it should take about a half hour. The plumber they sent did not know where to put it despite pictures that were sent, and notes written on the wall. Thankfully, it was only a half hour charge. I understand they need to make money, however, they should have contacted us prior to giving a quote for a job. My invoice says, install of a shower system provided by the customer. We will not be using them for the other shower system. We have another plumber coming out tomorrow to look at the job and give us a quote, which is what should have happened in the first place. This is not about the money, it's about the principle. As a business you made a mistake that you need to own. Not only am I frustrated, but this also put our remodel behind by two days.
