Eligible, no date for 3rd stimulus..

Eligible, no date for 3rd stimulus..
There are many of us who are unable to get clear and concise answers from the IRS. No one is willing to assist. From the beginning, our status has never changed/updated. Each one of us come from various backgrounds; single parents, families, etc, but one thing we do have in common is the "eligible" status regarding our 3rd stimulus. However, no date is listed...
Don't we have a right as taxpayers to know when we will receive it? If there's a delay, and why? This money was supposed to be "immediate", yet many of us haven't received one penny! A lot of people are living paycheck to paycheck..trying to determine if gas or groceries are more important. Meanwhile, nonfilers are receiving theirs, and those who have already received the stimulus are getting "plus ups" payments and our group has received zero ups!
We would like to know why our stimulus is delayed, and hope someone will look into this. Please advise.
