Car Dealership Fraud Concerns

Well I’m curious to know if it’s legal for a car dealership to sell a truck that they claimed had this entire off road upgrade package added to it but actually they just put decal stickers and added nothing. The deal ship does have an off road package called the T-Rock edition and when I asked what the t-rock sticker was they told me it was all these upgrades they do custom at their dealership. A few months after buying the truck I tried asking them about what parts they use because I needed to replace a coil spring but they told me that on this truck they just put a sticker on it and did no work. They were really difficult and dismissive and just plain rude to even get any information from. But the lied to me about the truck and told me it had this t-rock package when it actually did not.
