AAI job offer scam on Messenger with fake fees

Actually I posted about job vacancy in fb page then suddenly this guy popped into my messenger claiming to be as an employee of AAI in guwahati airport azara. He told me that there is a vacancy in his company so i can join. He took around 3.8k as joining fee, registration fee, and what not and now when i asked him to give my money back he isnt responding to my calls. Even if he responds his only answer is im managing money and I'll give u by this evening or tomorrow. Report this fraudster.
