Query: Reallly upset!

I am so upset with this product! I bought this trumpet for my sons first year of band. After the first week of playing the band teacher realized that there was something wrong with my sons trumpet. The second valve was bent on the inside. So my son has missed many lessons due to the condition of this trumpet which will effect his band grade.I am afraid that this will kill his spirit for learning music. He is a straight A student, and now this is going to lower his GPA. All that I have to say is SHAME ON YOU austin bazaar! Oh also the teacher made the statement that the brass on the trumpet of the trumpet was so thin that she felt that I was had by the company! I am so unhappy because now I have to buy another trumpet. I would never recommend this copmany for the purchase of anything. I am so sick of you I don't know what to do!
