I find one my images online but I never get paid for this image it was under Alamy but I never upload him to Alamy if I am correct only to one other agency. But not paid from them also. Never mind it was just picture but.... ? I already contact Alamy for any info about this sale, but it was not Alamy mistake for sure 

Like Falantus said, is the agency you put the image on a partner of Alamy?

Have you checked to see if your file is on the Alamy website (do a search). That would show whether your file is there legitimately via a partner seller or if someone else is claiming it as their own (I'm not sure if I've ever heard of that on Alamy, but presumably it sometimes happens.)

If a partner, be aware that it can take months for a file to show up as an Alamy sale, then more time for the money to clear, then it will need to be processed through your agency.

Finally, it is slightly possible that it's an honest mistake by the user. I happened to find one of my files on a book cover with a SS credit. I couldn't actually find it on SS, but I sent a pleasant email to the (very small) publisher to enquire. They contacted the designer and it was a honest mistake, they had a valid iS licence, but somehow had credited it as SS. The publisher was very apologetic.

Thanks for all responds, I have super fast respond from Alamy  and it was what i know - I must contact other agency a hope they will be same fast like  Alamy, it was sold in 2018, just I can not check sales online
