After you file

I have done all that I just did it twice in the last twenty minutes, and after I get through all that, they said that I have three cards and I need the last four digits, when I have responded to this, I have said that numerous times and still get no live agent, I get told by the computer to call back when I have the last four digits of my pre paid debit card, two of them that I never received, and the third I haven't used in over three years, so can you tell me the last four digits so I can get a live person on the phone, or email from a live person?
