Yeah, what the others are saying is what I'd do as well. It's not a high ticket item. But, I understand how you feel about their attitude. I might be tempted to write a nice letter to the people who have a stake in the company.
I wouldn't bad mouth them but I also would never recommend their products. Don't forget that their other products such as reels, rods etc. are not manufactured by the same companies who supply their line.
I've never understood why line manufacturers don't date stamp their products.
