Giving out other peoples information

I have received over 20 phone calls in the past two days from CDC on behalf of Discovery, asking for multiple different people, not one of them is me. They want to collect FICA documents from various people and they cannot even call the correct phone number, how can they be trusted with valuable documents.<br> Asked to talk to managers, none are willing to talk to me. If they call me again I will be taking legal action for harassment.
