We had been using Cantu Pool Service (in Edgebrook TX) for over a decade. We just fired them after finding one of their workers who cleaned the pools engaging in animal cruelty toward our new puppy. The dog screamed like crazy and hid in a dark space inside the house for a half-hour afterward. The person who did it, George Martinez, was actually defended by the owner--the owner does not care in the least. This is a BAD COMPANY that ENGAGES IN ANIMAL CRUELTY. DO NOT HIRE OR SUPPORT THEM!!!!! They are being reported to law enforcement and the ASPCA. They don't have a BBB registration, but that may be for good reason. Do not hire people like this!
