Threatened in Bangkok

I am threatened by the guy who found apartment for me. I say he did a good service and I felt he needed cash so I told him that I can give him small loan in a period. I gave him over three times Protected content , actually nothing.

Point is that after I had paid apartment, he went not polite and talked bad about me..I said "24 hours and you pay me back"...and then thunder storm started...He SMS me "One more SMS and I hurt you so much that you will never see by your self"...and I reacted..."11 hours left in a SMS from me..and a few mails from me "Why you never visit me?"..and so.

He is extreme crime back in 90th in Sweden and also he is not legal in Thailand..H told me, I hate Thai people and I hate Thailand...

What should I do?
