I accidentally summoned the devil! PLEASE HELP!?

I was playing around with the cereal in my bowl until the Cheeri-Os formed a pentagram and Satan appeared before me, knocking over my bowl of Cheeri-Os. He asked me what I wanted and I said I would like some more Cheeri-Os and he said fine and disapearred and my bowl was refiled with cereal. I then relised I made a terrible mistake! Did I just sell my soul to the devil for some Cheeri-Os!? OMG PLEASE HELP :(
