BTW How can I contact bbb. I looked at this website, I don't know how can I attach my package list which is evidence.
Thanks for all the suggestions. I will try my best. I will also report the result later when I finish this. I will also tell you the website I used to buy camera if the final result shows I am right. You know I am not a lawyer and have not final decision though I am sure this company cheated on me.
