Furious & extremely dissatisfied

I bought my car from Brits auto pedigree as one of my colleagues had got hers and looked very happy so I believed this would be a good place to start. To my surprise it clearly wasn't and still living the nightmare. Sales consultant Selby Prins sells me the car and sadly as a 1st time buyer I just believed it's a 2013 model with 38000km on the clock so there shouldn't be any problems only to find that I get stuck with the car in less than a month, I don't have the registration documents which even after the 2nd 21days has passed I still don't , I don't have service history, after I followed up on spare keys only when my dad intervened were they sent, I was told my 1st instalment would be January only to find that it's December(inconvenience 1), at 45000km I take care to service only to to be told I have to pay for it & wasn't made aware(inconvenience 2), after the sale was made I was just neglected as all of a sudden it's hard to get hold of Selby & no one calls or checks up on me. The manager Leeud rudely tells me he won't take the car back as I am unhappy with it and don't want a car I got stuck with in less than a month. Their service is really bad I want no dealings with them.
