Do you file a criminal case or civil case for not returning borrowed money?

Dear Sir or Madam,

A Moroccan citizen who lives in Dubai owes me money. I live in Europe and have never been to the UAE. I met this man in Morocco in 2014.

Later he sent me a friend request on Facebook. He manipulated me to loan him money via Western Union with various excuses multiple times.

It started when he was still in Morocco in 2016. He promised to repay me when working in the UAE. He moved to Dubai in 2017, but money requests didn’t stop.

I made six transactions between Jan 24, 2017, and Mar 9, 2018, total 1150 €. I have Fb chats (also a voice message) as evidence.

He promised to pay AED 500 per month but never paid. In Feb 2019 he blocked me on Fb when I demanded him to pay. On WhatsApp, he still promised to pay me when he could.

I tried to be patient because of the coronavirus pandemic. In Dec 2021 he blocked me also on WhatsApp.

Can this be considered a crime in the UAE?

Can I file a criminal complaint against this person online?

How is the limitation period calculated in this case?
