After less than 6 months is defective

I had bought because of the reviews and the price this machine as a beginner model. Times Viewed from the fact that I constantly the thread is broken and it runs quite loud, the needle me is two to three times broken. In this case, something must have shifted and now the machine sews no elastikstichen substances more. The repair cost should be about 60 Euro. I think a sewing machine should forgive a beginner even small errors like a broken needle ... I still give two stars because the Singer else do a pretty good job.
