Why the long wait

I filed my taxes with turbo tax on 1/31/19 and this is the first year I've had issues on 2/12/19 WMR simply said

 

"Your tax return is still being processed. A refund date will be provided when available.

Please Note:

For refund information, please continue to check here, or use our free mobile app, IRS2Go. Updates to refund status are made no more than once a day."

 

no codes no errors nothing and it has been this way since its now march 4th and I have no update on my refund, no letter from the IRS, and can't even get a person on the phone from the IRS every time I call I get the automated system and go through the prompts and get to the point where it has me enter my social and then says "were sorry due to high call volume we can't take any calls on the topic you have chosen good bye" and then hangs up this is so frustrating I have tried calling every day for the pas week with no luck. has any one else had this problem or know the cause?
