RENAULT BRYANSTON SOLD A CAR NOT ON THE SYSTEM

I bought the car and a service book was given days after it was collected. It broke down due to gearbox not working & taken to Nissan The Glen, it was discovered it is not on Nissan SA system, no previous history. Renault dealer was contacted about it but no resolution was found for the book or 2nd key never sapp****. Used car Manager & sales rep contacted from 21 Feb never provided any resolution to the issue. I visited them on 27 Feb 2020 after days of phone communications, that’s when they request Nissan to go ahead with diagnosis, but they can’t give the servicebook or 2nd key. After I told the manager that Nissan has confirmed that delays have been caused by Renault as there is no service book and the car sold by them is not on the Nissan SA system / record, he promised on 02 March to give a car to be used while waiting, then on 03 March, he states on the phone that only from Thursday can they look into this. I am now standing between two places, no transport means, no service book, no 2nd key, with a car that has no history with the manufacturer itself. Nissan SA checked stated that they have no single info on the existence of the car before I took it.
