Dude, you are running the gamut of red flags and your type of behavior screams amateur.
-origin country is well-known troublespot
-bombarding with messages on a Sunday (it's the weekend!)
-asking why are you ignoring me
Like others said, you have to see this from their perspective. The aff manager is a human who has to deal with dozens of requests on a daily basis, much less the weekend. Like most IT professionals, he probably has a desktop or laptop running 24/7 sitting on an office desk with Skype running. So it may look like he's reading your messages, but he's not. And even if he is, he's more than likely shaking his head thinking "Great, another jackass from Serbia with 0 professionalism..."
If you want to be treated like a professional you have to conduct yourself in a professional manner.
