EBK la Rochelle branch

I bought a car at EBK la Rochelle branch last week Thursday,it was a Ford Fiesta 2016 module.I was never told about the problems that the car has.monday when I tried to drive a car again it was telling me about gear box and Battery problem.Now I am stuck with a car that requires mee to pay close to 20k to fix it,I regret the day I went to EBK to buy a car.They are very unprofessional and just pushing sales.I am totally disappointed.Tried taking the car back the told me they can't help.Very useless
