Honest Johns Used Cars Bought a car 5 days later the transmission went out got the fixd 2 weeks later the transfer case went out Schuyler, Nebraska

I bought a car from them it is a buy here pay here. 5 days after I got the car the transmission goes out. they told me they would only pay for the cost to put the transmission in. I got another transmission for $400. They paid for the cost of labor. 2 weeks after the transmission was in the transfercase went out. I called them and they told me they would only pay for the labor. I asked to get a different car they refused, I asked for a price reduction on the car they refused and hung up on me. I havent had the car 2 months and two major things go wrong. The car is a 1999 ford explorer.
