Retirement tax questions

I called the broker (Vanguard) and was told to contact the IRS ðŸ™„

I pressed further and they tried to give me the payer federal id (which is on the form).  Document id is 11 characters.  Payer federal id including the hyphen is 10.  I kept pointing this out and the rep said this is all I'm authorized to give.  I asked for an on shore representative and was told to call back.  So I said then I call again and get an off shore rep and will be told to call back for a 3rd time?  Response was yes.
