Ya, that is a near miracle these days.  I went 7 working days trying to get in only to be put on hold and hung up on after 90min of a 15-30min hold message. 

Am getting such strange notices these days.  Missing estimate payments, penalties and interest on amended returns that were filed and paid (along with paying interest and penalties shortly thereafter) 1.5 years ago, IRS not seeing e-filed amended returns, etc...  I'd say at least 30% of notices have no real merit, just errors on the IRS's side.
