Brother Sewing Machine

I purchased this machine on 7/7/2020 and am returning it today. Followed all instructions on how to insert bobbin and upper thread. So I was ready to go, right? Wrong! When I started to sew all I could hear was this loud "clunking" sound like gears rubbing together. I thought maybe I had threaded it all wrong, so I started over and got the very same results. I only sew for pleasure and only lightweight fabrics and I thought this basic machine would be perfect. Not so. I have never had a Brother sewing machine - I've always been a Singer girl. I think I will go back to Singer.
