Can not uncancel content ID before end of month

So originally I was not going to be around for the month of May, so i decided to go ahead and cancel my content IDs after the April cycle. So I did that, as i have several times before. However the trip I was going on was canceled and I am going to be on during the month of may.
Today I went to reactvate, or uncancel those IDs so I can play next month. However, there is nowhere I can reactivate it for some reason. Next to my names it says cancelled and no options to change my mind. Any help would rock.

Thank You

Cancellation pends until the billing maintenance. Once you choose to cancel an ID, it stays that way until the maintenance, when the cancellation takes effect. You'll have to wait to reactivate until after the maintenance, so probably the 2nd or 3rd of May. Then billing for May will be delayed until the June maintenance period, and so you'll be billed for both May and June at the start of June.

Ok thanks. I just do not get why they can't be like other online games and bill you on the day, prorate etc...Owell lol
