I agree that you should call them and complain. However, I onced received something that I did not order and contacted the Post Office to see what my obligation would be in this case. I was told to call them and tell them that I did not want it and if they would send me a postage paid label, I would return it. If they chose not to send you the label, you are under no obligation to return it. Be sure and make a note of the person you talk to in case you need to prove that you called about it. I was told that the best policy is to refuse anything that you did not order. Not always easy.
