Severe realm roll backs

Severe realm roll backs started about 6-7 days ago and can happen at any point, sometimes it doesn't happen for a few hours sometimes it's every few mins and it rolls back a good amount of time. I've lost over 30 hours of work due to this and the members of my realm have lost alot more then that. This is a serious problem and has to be resolved ASAP I pay for this and I expect it to work properly.
