Bad Service and Empty Promises

my sister,nephew and myself went to view cars at the dealership which was close to closing time , and we were assisted by a gentleman Vernon the Salesman whom we dealt with As an ex employee i knew what to ask for, with regards checking for accidents . We asked if the car had a full service history, service books and we also asked for an HPI and like a salesman does promised that all would be there. we were shown around and then my sister set her eyes on a Hyundai I30 Auto 2013 model. Vernon then offered to take her on a test drive ,which she accepted, then she did an offer to purchase. This was on the 13.06.2015 at approx 12.30pm , finance was done and she was called to ask for the Deposit of R50 000 which was on the 19th June, she only got delivery of the vehicle on 26.06.2015, now there is an issue of there being no service books or owners manual and the HPI was not produced and Vernon seems to be telling her that this is adding to tne cost of the car , the mud guard which was promised to be sorted out has to still be be done.As an ex employee i know that the client has the right to the HPI which will advise if the car has been in an accident and we are still waiting
