30 points and usage for reducing bill?

[JONMILLS]

I have 30 points, i applied 15 to get $15 off next bill.

I have 15 left. Can i do it again or do i have to wait until the NEXT bill after that one to apply those 15 or can i get $30 off my bill? How will public mobile treat it

you don't have to wait for next cycle.  After you requested the 15points for $15, go back and request a second time
