I faxed to number that you advised above and called to IRS. They issued EIN to my LLC and gave me a number, but Operator said: IRS will fax confirmation letter during 1-2 months.You can fax it to both numbers, it does not matter to which number you fax it, the outcome will be the same. You should stop calling and just wait!
He said IRS have only one fax machine. Be patient
