I purchased a Terry's Orange in November 2017, biting into the 2nd segment I discovered a string like substance running through the Chocolate. I sent Mondelez an email and they promptly sent me an envelope to return the product to them. Now they have the evidence they ignore all emails and communication. I have never been provided with an explanation or what the object was. Now March 2018. VERY DISAPPOINTED
