!n 1998 I bought a living room Wenco 5-pane window. Ilost the warrantee paper. I called the place where it was purchased. They said they just went to computer 3 years ago and would have no record of my purchase. So much for IRS requiring 7 years to keep records. So at present I guess no one can help me. The window has a 10 year warantee. Do I have any recourse?
