Hello,,,, I bought an f64 8x10 backpack several years ago maybe 5 yrs. old now

I had a strap break at the bottom where it meets the pack.. Is there a warrenty on these packs ? I was thinking I read somewhere when I purchased the pack that they had a lifetime warrenty ...? Hard to believe the bottom of the strap broke instead of the top where the bulk of the weight is

thx
