they refused to give me the reward, saying because i am not at vip level platnium 4.
You aren't eligible for the bonus if you aren't platinum 5 or above ranked users. Because user receive VIP host after reaching platinum 5 rank and the monthly top player bonus reward is given by the VIP host.
I guess that's the end of this thread...
OP hasn't been active for a few hours guys, give them some time to read the replies and address them. I think that without any screenshots we won't be able to say more, but to me it looks like the problem is resolved. OP thought that VIP status was the only requirement, but it wasn't. Sorry, OP. They don't have to call the bonus VIP Platinum for it to have a platinum requirement. It's up to you to read the rules.
