Bests & Worsts Reviews from Amazon

I ordered 2 of these and love the one that was not defective. However, the spouts on the pink one had a dent in it and the tip fell off. We got to use it for 1 week. I am unable to contact the seller for some reason and since I had registered the prof it with yeti, figured it would be no big deal. However, I was told by the yeti that because it says seller: AMAZON LLC, it is a possible fraud and they will not stand by the warranty. I am so disappointed in yeti and honestly just mad. When asked what registering the product does...I was told that it doesn’t help with the warranty, it’s just a way that yeti can thank you foe the purchase. Super disappointed. If someone from Amazon would contact me in regards to this, It would be greatly appreciated!
