If I could give this company a negative rating, I would. They certainly do not deserve a 1 star. Cannot get a call back from anyone, my pool has been green for a month, they have automatically deducted 3 invoices from my account in the past 4 days, totaling $560. In 4 days....for a green pool. I have paid them almost $2,000 in the last 6 months, let me reiterate for a green pool. A small, residential green pool. I can't get a call from anyone nor will they stop deducting money from my account. Beware of these crooks!
