So far I just got one call from them with no message of course. But I still look these numbers up to see if anyone else got a call. These unwanted calls don't always come from toll-free numbers. Sometimes they look local.
I've been calls from collection agencies since 2011, looking for someone else. I never did talk to them. I've had my phone number 20 years, so they are calling on some really ancient debts of someone. I don't have debts, have great credit, and don't owe anyone anything: Money or anything.
