ase has been already escalated是什么意思

今早收到support的回复，求问这个escalated是什么意思啊？？
In regard to your query, your case has been already escalated and is still in process. Please check with us at a later date or wait for our response once there is an update on the case.  

Escalate: 原意是提交到更高层面来处理。看邮件，似乎也是这个意思

是意味着审核时间延长了？
