Have you tried to change your VPN into an Indonesian IP just as said by the rep? and you'll probably gonna those promos that locals gets.
Because the account is already registered as international user, it seems that even using an Indonesian IP will still not get promotions like when registering on a local website. Before registering, I asked @roycilik first, the web that can be opened in Indonesia without a VPN, and I open it via bk8btc.com, without a VPN it's no problem. So my account became a local account because the initial IP recorded was an Indonesian IP. if there a migrate account options, maybe can help to be local user. if not, his account will remain as international user account, CMIIW
