If you're having no luck with the manufacturer take it back to where you bought it, show them the rope is defective and get them to replace it. Then the dealer can take it up with the manufacturer.
I'm not a lowyer so i could be wrong, but i'm sure there's some consumer protection law saying that a shop ower has a duty of care to ensure the products they are selling are not defective (to a reasonable extent).
The dealer has a relationship with the manufacturer so make it there problem, not yours. |
