Zero after sales service.........

They guys at Mazda Clearwater were wonderful to start with. We bought 3 cars in 2 months making them a fair sum of money in those 2 months - easy money I might add, they did not need to come and see us and negotiate or anything. The 1st car that we bought 2nd hand was a Rav 4, there is a tear in one of the back seats and the cruise control does not work. I have had endless broken promises about getting these items repaired and nothing has happened. The 3rd car we bought 2nd hand does not have a log book so the questions is - were they lying when they said "full service history" because there isn't one or is that simply an over site and it is lying on the salesman's desk. I am absolutely horrified at the lack of after sales service received and I would like Mazda Head Office and the Dealer Principal to know what happens to their clients once they leave the "floor".
