The pool is located in a fenced in locked pool yard. No children are present. The pool cover has been operating for 6 years. The main travel bar fell out of the track. The plastic slides had disintegrated and needed replacement. The service person arrived 2 business days after call, refused to service the cover as he said I needed to purchase a new cover and they would not do anything to make the cover work until I bought a new cover. The cover was leaking along a fold that has been in the cover since their original installation. It is the height of my season, I use the cover to maintain heat in the water during the cold evenings. I have one more month of renters who expect warm water. They cannot repair or replace the cover for approximately a month. After begging them, they left the parts and told me I could repair it myself. They charged me over $100. for this "service".
