I recently bought Samco knock off silicone hoses on ebay from China. The listing said the tolerances were .5mm.
When they arrived the tolerances were more like 5mm. I told them the ad was misrepresenting the product that arrived and explained that I shouldn't have to pay to ship it back to them since they made the mistake.
Unless the item was listed as a broken fender you should try the same.
They emailed me a shipping label to get their hoses back today.
