Cruel and uninterested in pet

I took my Eclectus parrot to the above Dr. He is only 9 months old and it was his first to the Vet. I took him there to get his wings, beak and nails seen too. His one wing was clipped in September 2014 but I have been struggling with it as it was not cut properly and wanted it to be seen to and perhaps advised as to help get it to grow better, as he is getting irritated with it and bites it alot. This vet got an \assistant"to come and handle my child. He used a leather glove and I explained he was very gentle and could be taken out of the carrier by saying step up"
