the other night i rented a movie from redbox
the very next day i went to stop & shop to return it and i selected return and put the movie in the slot and walked away
usually i wait to make sure the screen says "return successful" but i was really in a hurry
Since then i have not recieved any red box email telling me the movie has been returned or i will be charged for another night

shouldn't i have gotten an email by now?
will they charge me for any additional nights?
