If this happened to me, I'd send a tip to the FBI[1].
You tried to report to apple. You didn't like the way they "treated" you, so you decided to sell it on black market. The black market person tried to hack you. You then went to the fbi to complain about how your black market buyer treated you?
Am i missing something from this story? That seems like a really bad plan.
On a serious note, I'm glad researchers like you exist.
