Piece of Metal Found in Large Can

I opened, and partially used, a large tin of Nestle Coffee Mate. Midway through the can I discovered a narrow, tube, shaped, piece of metal approximately 4” long. At first I thought it was a nail, but it had no head.

I contacted Nestle and they asked me to send in the piece with the prepaid courier package that they supplied. They gave me an instore coupon for the sale price of a can of Coffeemate to replace the one in complaint.

They did an investigation and concluded the piece did not come from any of their machinery, so therefore, the pin was not inserted in their factory, and there would be no further investigation. In addition they voided my coupon for the replacement.
