Worst Experience for buying my first car

I was told by the sales agent that the 2009 Ford Fiesta had a full service history and that my vehicle was in a great condition. I then proceeded to buy the vehicle as it has been looked after due to the fact that it had a full service history. I signed the document and paid my deposit. I had to wait 3 weeks to receive my vehicle due to the fact that it was their year end. When i finally received the vehicle with the service book I noticed the last service done was in 2013. FOUR YEARS AGO. I then called the agent asking him about it. He said he will request it and get back to me. After 3 months of nothing and my car that was literally falling apart I called the branch manager. He finally came to me a week later with the response he can't find it, it does not have a service history. He then arranged for my car to go the recon centre so that they can repair what they should've done in the initial recon that took them 3 weeks. I got my car back in the time promised (one good thing). But despite that, certain things have not been repaired. I have sent an email to the manager as well as called the branch and left messages for him about the things that still are not working. 2 weeks later not a single beep. I asked the way forward as my consumer rights have been violated, the response that I got came down to NOTHING.

3 of my CPA rights have been violated and now I am sitting with a car that not even they can repair.

This is just half of what happened but this is what upset me the most about the experience of buying my first car.
