Caller type: Debt Collector
Number has called multiple times. First time I answered. Lady claimed to be a debt collector trying to collect a debt from a hospital service my daughter apparently received at Johns Hopkins in Maryland a couple months ago (she's never been there seen there and we've since we moved out of state last year). Lady asked me to confirm her social security number for "their files". When asked the dates of the service, she said she could not confirm anything until I gave her the social security number. I said I would have to check into it and hung up. Seemed fishy to me. I believe it is spam looking for information.
