WE bought a camera 2

Question

WE bought a camera 2 years ago. We had a problem with the lens and we sent it back for repair the first year. And ever since then it had gotten worse. Spots on the camera and more. It barely get used and it is so frustating because it Cost 300 at the time we bought it. It is not right for this to happen. And I need to talk to someone that could help us.
