How long does it take for blizzard to reactivate my account if i send them a money order in the mail?

My account was in a negative balance and the only way for them to reactivte it was to send in a money order in the mail and i was wondering how long does it take for them to receive it and then activte my account.|||Who's Blizzard? As in Blizzard Entertainment? If so, then expect it to take a few weeks.
