Total unprofessionalism and lack of feedback

Worse service delivery ever !!My mother bought a ford eco sport brand new cash from Imperial Ford and Mazda and from day one the car has been giving endless issues with the auto gearbox . No one in Ford SA seems to know how to fix the shutter in the gearbox . Please share with me how resetting a computer will fix this problem?? I have had enough of these lies from the dealership and i request answers now ! I suggest Ford SA or the dealership pay her back in full an take back the worthless car they sold her . This car was bought in 2016 and is about to run out of warranty for a car which has only been driven for about 20000km . Who is going to take responsibility and just say we can not fix the car and here is your money back. Never in my life have i seen such unprofessionalism from an well know car manufacturer its about time that someone step in and call it quits and bite the bullet and take back the beyond economical repair vehicle and give her a full refund so she can buy a car that actually drives as it was intended to do. I will be making this statement viral and send out emails to the ombudsman because we just had enough and it's about time we get some fuel on this fire because sitting back and hoping for the best does not work . Ford SA and Imperial Ford and Mazda expect to hear from me soon .
