Very unhappy client

I would like to inform you that I am a very disappointed but yet faithful client that have been supporting Mccarthy Toyota n1 city (Automark). I bought myself a Toyota corolla professional 2013 model approximately one year ago and have experienced a number of major problems with this particular vehicle. In the first five months I had to replace the back brakes and due to this it has caused the tread of my tyres to disintegrate rapidly. I brought it to the attention of the Mccarthy (Automark) n1 city branch manager that has been very agitated by my complaint. His response to my complaint was a case of normal wear & tear, which i fail to agree with. I am deeply saddened by the fact that he has taken my case very lightly and of little importance.I am also aware of the valid warrantee and guarantee conditions of the contract but i am afraid it is unfair to me as the customer of Toyota Mccarthy N1 City. I am currently now caught in a predicament of major gearbox malfunction which is being repaired but my question is, what will happen when the service guarantee and warrantee expires and something major goes wrong with the gearbox again?<br>
