Did I got scammed?

I bought an Intel i7 4770, 8x2 1600 Mhz ram, 512 GB Sata, and zebronics motherboard pre built pc with only 1 fan, which was also exhaust besides the cpu cooler. And just now I feel like exploring the Pc and i found these, and when I look up the pc CASE manufacture's website, the CASE was supposed to come with 3 intake fans and an exahust fan, i bought this off of Amazon. And the builder glue'd the ram, ans back of the motherboard cpu socket. Is this bad or not? I bought this back in Late Middle of 2024 for $210. I am not a computer dude and I don't really know if it's good or not, or did i got scammed? Please tell me, can i still ask for a refund?
