Sir if someone took my money for my visa renew...

We would like to inform you that it’s clear that you were under fraud so you have to file a complaint in the UAE court and the Public Prosecution and explain the details and mention the names of the people you have dealt with and the persons who know the case details and you have to claim for your money.

So according to the UAE Penal Code, this is fraud and the penalty is prison and fine as below article states:

Article (399)

Detention or a fine shall be imposed upon any one who seizes, for himself or for another, a movable property, or obtains a document or signature thereon, cancellation or destruction thereof or amendment thereto by fraudulent means, or by assuming a false name or capacity, where such an act leads to deception of a victim and leads him to surrender. The same punishment shall apply to anyone who disposes of real estate or movable property knowing that such a property is not owned by him or that he has no right to dispose thereof, or if he disposes of a thing knowing that it has been previously disposed of or contracted upon, provided that such acts cause damage to a third party.
