I need a letter to inform about misconduct and indiscipline in following code of conduct

yash-raj1
I have come to notice a few architects misusing the social media for promoting their firm by uploading pictures from the Internet and calling them their own projects both of them are non architects and are charging way less than valid price set by the coa code of conduct which is making it hard for actual architects this kind of scam should be stopped. I have the proof that the pictures are from abroad sources.
Can someone please help me write an email with good English to the coa. Please help me with the format for it
