I feel scammed by this indie yarn dyer — need perspectives

So I am a fairly experienced knitter but I’ve never purchased a yarn kit before. Usually I just pick a pattern and source my own yarn.

I just bought and received my first kit from a brand called Yarn Love Yarn, I’ve purchased from them before (mainly for sock yarn) and have really liked their products. Recently I saw a Halloween sweater kit they were selling and decided to get it because I’ve never done one and it seemed like an easy way to just get exactly what I needed all at once.

I assumed that it would be the same quality as previous hand dyed yarn I bought from them and didn’t think too much about it. Imagine my surprise when I get the kit today and it’s all Cascade Yarn. I was so confused so I double checked the listing thinking I made a mistake but after another read through I feel like the listing wasn’t transparent that these were not her hand dyed yarns. I’m okay with the yarn and will probably keep the kit but I feel kinda duped.

Idk, is this a common practice? Should they have been more transparent? Am I just dumb? It’s been bothering me because I guess I just feel misled and annoyed by that, it’s really turning me off from this dyer.
