sorry if this is the wrong tag i dont know anything about laws. i am so scared. i live in the uk but i sent the package to america and i have never dealt with fedex before. surely this cannot be right?? there is no chance in hell i can afford to throw more than three thousand dollars at something as meaningless as this. why would it be this much? is there any way to make it go away? i have no source of income. in the uk where i am from they hold the package until the customs fee is paid. why would they ship it MONTHS before informing me a fee even existed? i feel trapped. can anyone help me? i dont know what to do.
