I am having an issue with a mechanic and would like to know whom i may complain to... The issue is the mechanic advised me that my Audi's auto was on its way out and that i needed to by a new one or reconditioned one.. i brought a second hand one with 6 months warranty which has now been installed but i still have the same problem.. I have since then taken it to the place i purchased the auto from and he placed it on a testing device which clarified that nothing is wrong with the auto... What can i do now that i have spent 00 on a second hand auto and the installation of it when it was not necessary? Please help!
