Out Of Warranty

Hi

So i bought a vehicle from Imperial Select parow that moved to Brackenfell now So my car had issues and was discovered my car is out of factory warranty cause the service was done late not by me but by Imperial Select

so with a weeks back and forth the car was fixed by paying for it but Imperial Select paid for it

now the issue is the cars warranty was only to expire 2019 but i only have the 2 months now going 3

now i called all the people involved and all pulled out of the deal now i am stuck with no piont of contact

and no one wants to take accountability for the vehicle cause it was declined from Renault and they dont want to take the blame for there doings

i want to give the car back unless i get a letter stating they will carry and cost we good for now we not
