DEDICUBE Server down, no ticket, PM, phone, LiveChat respond in almost a week, still send me invoice

Hi everyone.

I rent a x3470 & 2T server from DediCube(BoltVM, SiFuQi) Apr 12, 2015 for backup usage.

At Dec 6, 2015 after i reboot my server, it went down, and i can't manage it through DediCube client portal anymore.

So i send a ticket to DediCube, no respond within 24h. then i send a PM to Steven and try to contact them through phone and LiveChat(SiFuQi) no repond either.

Today, i come here and ask for help, there is a lot important data in this server that i don't want to lose.
