Extra Policies Paperwork not Updated

My mom bought a new Renault Sandero 900T Stepway last year in June. The gearbox was faulty & they replaced the car with a new car in approximately August last year.<br> <br> My mom is now in the UK and I am using the car (as arranged). When taking it for a service I was advised that there is no extended warranty & the VIN number is incorrect on the documentation. After looking into this problem we found that it seems as if someone neglected to update the paperwork for the Maintenance Plan as well as the Minor Damage Plan. My mom was advised and assured at the time of receiving her new car, that everything had been altered, but alas. <br> <br> I have contacted the people where my mom got the car from and the manager says that he is sorting it out, it has been over a month and no progress has been made
