I can't believe the lack of service...

I am very dissatisfied with the service I have received from Hyundai The Glen. I have purchased a car there previously and had the greatest service, which prompted me to buying a second one when I was in the market again. I test drove the car in question and started the finance deal on the 17th October, arrived at the dealership to take delivery of the car on the 31st October. Ample time to fix the things mentioned at test drive stage, right?? 5 days later I take the car back as all the things I needed fixed were not done. I have been getting the run around ever since then and even now as I type this complaint I still don't have the car that I am supposed to pay for. I rather have a loan car that dont like.I feel that the guys are not taking me seriously because I am a woman? I am not one to complain but that's my feeling at this stage! Even on the day when I picked up my new car, I was just handed the keys and sent on my way. No pictures nothing, for my special day... Well my special day that has turned to ****. My hands are tied and really feel that this is my last resort in being heard. I'm at the point of cancelling the finance deal, but this will just affect me negatively.
