Correct, the IRS is quite difficult to reach and it may be a challenging to track information about your refund and / or stimulus. Here are some more links that could help.
If you didn't receive your stimulus and it went to the form of a refund due to the Recovery Rebate Credit on your 2020 tax return, please check this link for more information.
If you never received the stimulus at all and did not declare it on your tax return, please check this link.
Here is the link to see your Online Tax Account.
Here is a TurboTax article with the latest information about the third stimulus payment.
