Hold on
You bought the item out of compassion for the lady? So you do know that you are buying a fake and your main purpose then is just to give her $40 out of kindness, right? :suspiciou
Don't mind me asking but why are you changing your mind now? I trully feel that the moment you made that decision to give her the $40 'charity' its considered lost money.
I don't think its right to threaten to report her to the mall security. I mean, of coz you can do anything you want, but its like taking a personal check that you made out to charity back and making threats just to ensure that you get your money back?
Besides, if you are tight with money, why would you buy a fake bag for $40 ? You shouldn't even be 'splurging'...
I am not poor but $40 is still a lot to me.
Seems to me that you are having a 'buyer's remorse' and you are trying to use threat to get your money back.
Neways, good luck with whatever you chose to do.
