recover days of premium

Good afternoon guys, anyone know what I can do to recover a few days of premium, formatted my computer and when I logged missed a few days !!! :(

i think that wired case it dosn't have any problem with a format as i know maybe i'm wrong it only need your hardware number but if so i think best option is send a massage to moderators then he will look for it

If the moderators dont want the massage, I'd take it. :- )
