From his thread, he had created a self moderated topic. It does not look like he was offering a considerable amount of money for promo stuffs. You can include the amount in the op to show how much you were assured to be given for the service. Also from profile , he was last active at june 2 right after the promo ended. All you need to do is keep an eye on his profile and wait for him to get online.
I messaged him way before june 2.. I have sent him many messages before he was last active..
