After you file

The irs website says that it does include weekends it's NOT 21 business days. Please don't give false information. I was done like this 2 years ago and it took 18 months to get my refund with a 300.00 interest but here I sit again waiting. I'm not getting my hopes up for I've been through this already. All they will tell me is random returns are selected for further review. My status bar is gone and it says still processing a date will be provided once available.
