Pathetic Service from Toyota Pinetown

My toyota raider had a a vibration on the front wheels. Wheni picked it up and reported it to the dealership t the time of service and within warrantee period. I was told that it was nothing wrong and that the brake shoes needed adjustment of which they did. The issue did not go.away and at the next service and on taking the vehicle to pinetown,.I complained again. I was told that it was a disc issue.. I also found out that the vehicle is now out of warrantee and that Toyota will not cover this. The vehicle was doing 50 000 when I complained. I feel this is very ********* of toyota to have waited for the vehicle to go out of plan and then o personally charge me for the replacement of the discs. Further to this, the service manager had a major attitude, gave me all excuses. He .was not helpful at all. He point blank told me that there is nothing he can do. I asked him to take the matter up with Toyota SA as the vehicle discs should not give up at this low mileage. It's a factory defect that they should look into. He said he will check and revert. At the time of typing this after 2 weeks, no feedback. There are others whom experienced the same issue and the discs were replaced. I find this to be very unacceptable and it questions the integrity and the quality of service of the dealership. Hoping that Toyota SA will assess the matter and resolve this soonest.
