Still no refund, and when checking status on IRS website it writes: We apologize, but your return processing has been delayed beyond the normal timeframe. What to do?

Only the IRS can give you any information about your return. They are telling you that you will have to be patient. 

thanks. But calling IRS [phone number removed] sends you to a labyrinth of messages you can not escape, and which is completely not helpful for this case.

The website also does not show anything. And there is no chat or email option.

Waiting from April to end of September, and nothing yet.

How long should one wait? and is there an option to learn what is happening?
