My name is XXXXX XXXXX I'd be happy to answer your questions today. I'm sorry to hear that this has happened.
What you're describing is a violation of the Fair Debt Collection Practices. It's illegal for a debt collector to call consistently or to call at hours that should be known to be inconvenient. If you send them a letter, via certified mail, telling them to cease contacting you immediately, they must do so. Keep a log. Make notes of every time they call. When a debt collector violates the FDCPA, the consumer can sue for up to $1,000 per violation
. For that reason, if they will not leave you alone, you may want to contact a local attorney who can help you sue. This site has some sample letters that may help.
It is possible that they have an address for you, however, the purpose of these companies is to try to get money from you. They're not likely to show up or become violent. Keep your doors locked and be vigilant. If you see anything suspicious, call the police and they will take care of it. But you shouldn't have any problems.
