Best Change Filters in Phoenix AZ

I originally called Poolman for prices on servicing my pool and wasn’t impressed so I went with a different company that I was very happy with. Unfortunately Poolman bought that company. Since the purchase they have not provided me with any proof that I have agreed to use their service, they make extremely rude calls demanding money yet can’t or won’t provide any type of billing statement or signed agreement to use their service. When they did come out they didn’t have the proper equipment and had to use mine. They have back washed my pool multiple times down the side of my house without using a hose and made a complete mess of my landscaping. Most recent was a call demanding I pay them over $1000.00. When I asked them to email me a statement showing why I owed them any money they got offended. They sent me an email that requested payment for a balance due but still no breakdown of charges. As of today’s phone call they have me a completely different amount they claim I owe and i still had to demand a statement with a breakdown. I still have not received anything from them as far as a contract or agreement or even an email to have them service my pool
