Refund

I e-filed my return on 3/3 for TY 2020. It has been accepted. I know it was received because the SSA sent me a letter that I am now getting $4.00 more for my retirement  based on my 2020 income. When I query the IRS "Where's my refund" it get the standard still being processed. When I check for status of my 3rd stimulus payment, I get "not enough information" etc.  I did not receive a 2nd stimulus, so Yes, I have an amount on line 30. If this wasn't bad enough IRS has yet to send me my refund for 2019.  I requested a transcript for 2019 and it shows a credit (they owe me) of over $5K (just for 2019).  This is really putting a strain on me that the "interest" they might pay will not relieve.  How can I resolve this? I've tried to call. I wrote to them in December and have received no response.  This is extremely irritating! Thank you for any information, suggestions.
