Query: Poor quality

My daughter pulled every other earring out, I was very pleased with this one. However after about 6 months the front of one of the earrings has just come off with the screw back left in her ear (which I'm not sure how to get out). Surely this is not the kind of quality one would expect from a good quality silver earring? I am frustrated and disappointed.
