Appauling service.

I purchased a double set of AMC cookware about 40 years ago and have always looked after them well. I was told that they have a life time warranty, however, the one large pots handle broke off. On returning the pot, they told me that it can not be repaired and that I need to purchase a new pot, which they would give me at a reduced price. I am not happy at all with their service, f they advertise a life time warranty, that is what i expect.
