This organization is extremely rude and inconsiderate. They never had my current address and show up as *AT&T Fraud #* when they call your cell phone #. I called after I received a derogatory account, after the representative said why would I do something to help your personal credit score. We tried calling you and that is enough. Terrible organization, don't understand how they are a debt collector. They should be shut down, clearly AT&T thinks they should be.
