Digital Marketing Scams

I think y'all probably know this but Digital Marketers have been popping up like crazy everywhere. Most of them are scammers, but even the genuine companies are unprofessionals when it comes to delivering results once their Fee is paid. This Pear Org in Dehradun is absofuckinlutely shameless. Ghosting their clients, no updates, no proper communication etc. Idk what's the best to teach them a lesson rather than going the legal way because then would eat up a lot of time and efforts thanks to our judicial system. Any suggestions, I'm open!
