how to deal with this problem

![alt text](image url)

when i entered the game ,it showed the words :'Your account was currently suspended, If you have any questions,please contact us through the official PSO2 website.【No.816】

PS: i am an asian player who went to play steam version PSO2,and i used the VPN to play that game ,maybe the reason why i can not play is the ip address. At present i just only wanna deal with this question... it actually puzzled me for a period of time........

Im not even sure anymore about whats been happening regarding suspensions uhhh.

@Lwyu i just use the VPN and change the IP adress from time to time to play the game about 3 days,and another day my account was suspended when i started the game,
