How sure are you that you are the first player from your country? Are you the only one with the internet over there? 

Jokes aside, you could have done something that triggered their system to flag your account, did you use VPNs to access the site? Share Wi-Fi with some other people/family members? Share your device with family members? Use an internet café or public Wi-Fi to access the casino?
You have to ask yourself all this questions.
