Any one having problems with the after sales service from champion motors?

I brought an suzuki swift recently and the brake having problems but i was blush off by the customer service that there's nothing wrong with the brakes when i went down to champion motors to log an complaint. There's also bubbles appear on the roof top and the bornet of my car. They had it repaint but the jobs was suck! Now my car paint becames patches and uneven. The paint work problems appear one week only after i brought the car! Had request since then to had my car change but it don't seen to work. Any one out there can offer an solution to my problems?|||Where are you, and how old is the car?
