I have been getting calls from a debt collection agencies every 2-3 days for the last two months. They mentioned someone who has the same last name but different first name in all the voice messages. They finally left a phone number that I could call to let them know that they had the wrong number. Apparently, the person who owned a phone company $$$$ gave them my number when they opened the account
The calls had since stopped but I thought I'd better check my credit score just in case. Someone told me I could do that for free as many times as I like using CreditKarma.com. It provides a credit score generated froml TransUnion and not a real FICO score, but seems good enough for periodic credit monitoring. I had to enter my SSN and verify my identity but it was pretty easy otherwise.
