Terrible Service and product

Like the previous complaint . Very bad service and attitude and filled in a email form about the complaint on Zodiac MX 6 on two of my pools where the belt comes off and due to this streches the belt and damage it . The pool care guy also complain that most of these units purchased by the developer has the same issue . Zodiac refuse to act due to the fact that i cannot provide proof of purchase . Maybe i should submit my R 3.6 mil house purchase contract . This is clearly a design defect and a horrible product and company to deal with
