,All the immigration offices have a form you fill out at the immigration office that says your embassy doesn't issue the letter, you can't travel, etc.
Remember the last day you can apply for another covid extension is Jan 29 <- that's the day the order allowing them expires. SO get over to your immigration office and see how you apply for a 60 day covid extension.
IF you have an email from your embassy stating they don't issue the letter or a screen grab from their website take it with you
