I called Aerus Canada Monday afternoon about replacement hose, and what the part/service number is so I could order one through the local branch, here it is late Tuesday afternoon and they still haven't returned the call. As I said in a previous posting, I know a franchisee, we both looked up service bulletins and product numbers on the Aerus inventory system, and got 0 for inventory. IF they do have any, it would be news to me and the franchisee.
