Suddenly, parts keep breaking on my brand-new serger Sewing Machines Parts and Sales in Los Angeles

I got a serger or about a month ago and had been using it with absolutely zero problems for the past month. I had rethreaded it several times and worked just fine each time. Today, I was trying to serge something and I guess I stuffed too much fabric at once through the feed. All of a sudden it made a loud clunking noise like the sound of sewing machine makes when it is making a “Birds nest”. The right needle snapped. I opened the serger up to look inside and did not see anything out of the ordinary. I change the needle and completely re-threaded the searcher. I started to sew again and it started making the loud clunking noise again. The left needle snapped this time. The fabric that had come through the machine did not have any stitches in it. A part of the surgery came flying out when the left needle snapped and I have included A picture. I do not know where this part came from. It appears to be bent as if it got caught somewhere. Any ideas as to what to do? It is a brand-new serger and it was working just fine until that first needle broke and now it no longer works. I had not changed any tension or anything like that.
