I pressed '1' to speak with an agent, since I am on the 'Do not call list'. They identified themselves as working for 'Card Services'. When I asked for more information about the company, they hung up. Calling the number just results in dead air and a hang up. I did get another recorded message once - very garbled introduction, something about 'buying calling lists' followed by 'if you want to be removed from our lists, press 1'.
