yes they are crookard.
they buy expired credit files from credit card companies.
at one time the person has had a credit card purchas and what happens is midland credit buys the old file.
the creditor who at one time had that file turned around and sold it.
now even tho that past bill has long since been paid they will call or hound the victom hoping that the victom will simply pay the bill again.
dont pay them they are a scam company.
