I owe an old utilities bill.?
Move to a different country where your old credit report won't follow you. If that seems a bit extreme, I might recommend contacting your creditor and making good on the balance owed. If there is another provider in your area, some utilities, depending on where you live, may be willing to extend you service with a very large deposit (bond). You'd need to contact them directly and make an application for service to find out.
