My son bought an unlocked iPhone and my sister added it to her plan. Later, when she removed it Verizon marked it as lost or stolen. My son can't activate his $500 phone because it is marked stolen by Verizon. It isn't even a Verizon phone. My sister called and Verizon was supposed to take it off the list but it still can't be activated because it still says lost or stolen. What can we do?
