Business ProfileforLinric Auto Sales

On 2/5/2022 I bought a Jeep liberty and was told that there was no rust on the car. The price of the car was ********* and there was a 3 month power train warrenty included in the price, I took a loan out at five county credit union for this vehicle. I brought the car back around Monday the 21st (not 100% sure it was Monday but right around this date), because I heard a tick in the engine. After they looked at the car they said that it "was totally normal" to have a tick in the engine, and they actually added something into the oil which masked the sound. Not being the most knowledgable person about cars, I did research and talked to people I knew (mechanics, people in the auto sales industry, and researched the noise I had heard). What I learnt is that it is a major issue to have a tick int he engine and it is likely a problem with the engine, I also found rust which I was assured did not exist on the car. I then started looking at the paperwork on the warrenty only to find out that my SIGNITURE WAS FORGED on a paper that I had not seen.The paper is the car protection plus and is for the warrenty included in the price. When my father confronted him on this, he denied forging my signiture, but yet me and the person with me can both attest to the fact that he did. I am seeking to get them to buy back the car.
