Well you have done your $300 that is for sure, but you should text her to tell her that you posted about it on the forum and she is going to lose a fuck of lot more money by the bad publciity than she ripped off you.
She does not care about bad publicity, they are scammers, they get another phone number and they will continue to scam.
I have already said it more than 3 times, bank deposits never!
**Being second is to be the first of the ones who lose**
