I'm receiving not so nice phone calls.

I agree, I’d try the parents first, If there bolth useless exuses for human beings, then retaliation is in order, Personaly prank calls are the most annoying and childish thing anybody could do, and I’m not much older than these Girls, I dont even find it funny from friends, but seriously if it doesnt stop after the mature thing to do has been done, then the Power of nyspeed has to be called upon.
