VIP

[Swoots]

Hi guys, a few months ago I got VIP membership shortly before I had problems with my internet provider and had to make a switch, it's my first time connecting to the servers since around may, and I see that my membership has ran out. I was under the impression that the time was only consumed whilst I played/was online, but I guess that's the wrong information. 
I was wondering if by any chance it would be possible to recover the VIP membership time that I haven't used? Thanks in advance.
