Me too! some guy said he had a mastercard account in my husband's name for collection. Wouldn't give account number or other info. I told him the only MC card we had was paid off 20 years ago. Then I hung up. Not wasting time with stupidity.When I looked up the number I got: http://www.myaccesscorp.com/index.html. This company acts like a middleman to hide who the caller is from what I understand.
