They called me looking for my daughter so that she could pass a message on to my son, but wouldn't give a company name. I took down the phone number and called them back. I got through to a switchboard but the woman refused to give the company name as they supposedly dealt with "sensitive information"

Caller: They refused to say the name of the company

Took a message for my boss. They refused to say the company name due to personal reasons. Only that it was a personal business matter.
Looked them up and the name is Credit Corp.
