Switching from Plus to Premium with points

[Coran 0]

I'm wondering if I use my points to upgrade to Premium, if it will revert to Plus (which I'm on now) after that period? And also, how does the charging work. If I have 6 months of Premium points, will my current paid plan for Plus be extended for 6 months (as though the points paid for those months).

I would assume that whenever your anniversary cycles you would be charged a Premium rate or would most likely go to Basic if you opted not to do that.  The Plus plan has been dropped and folks staying on it are able to but no new sign ups.  Best idea would be to contact EN for the answer.
