David Chang owns Plan 202, Touch Translations, and some other businesses that he creates and then makes disappear when people start complaining. He scams not only clients but employees as well. There are reports about him on www.ripoffreport.com
Be careful with this person because he is a professional scammer. Other names he uses: Bill Trinh. He impersonates others like his own employees. David Chang has been scamming people for a long time but always for amounts smaller than $500 so that small claims courts don't pay attention to them.
David Chang is really dishonest and takes advantage of honest writers, translators, and students.
