Turn Up The Heat

I recently did a freezer hex on my ex. I wrote his name seven times, folded it away from me and chanted "Karma T Capiet" three times before actually saying the spell. I put his name and his photo into a jar along with pepper, cayenne pepper, hot sauce and hot water, then put it in the freezer. That was a week ago and hes still acting like a jerk. Is there any way to turn up the heat on the hex so he feels the karmic bitchslap of his actions?
