Not honest and causing an inconvienience

I bought my car a Chevy Cruze LS in late November 2015 and drove it home on the 28th of November with no spare key or service book and to this day I am struggling to get from the sales man Raymond . At night it came to my attention that the rear break light and passenger spot light aren't working, the rattling underneath the car was unbelievable and the screeching breaks out of this world. Most embarrassing. I took the car in and they kept it for they day, when going to collect it they had replaced the bulb for the break light but said they where waiting for parts to deal with the rattling and screeching. I took my car and waited for the call once the parts had arrived as they said I should seeing that I was under warranty. Eventually I took my car back 3 or 4 days later seeing that know body was calling. They gave me a Chevy Spark for a week. A gentleman by the name of Alfie at the workshop said they had actually found a few problems with the car including shocks and more. I just wanted the rattling and screeching gone. I still don't have a spare key, the car still rattles and screeches and I can not activate my service plan because they cant give me a service book. Help.
