I have a co-worker here in UAE, who made a fake google map review using a fake google map account(newly created) just to ruin my reputation. What should I do? I what him to teach a lesson. I know for a fact that posting negative reviews in uae is illegal. Aside from complaining to HR(coz I know HR cant do anything) where else I can complain? Please help and give advice
