What should I do if my work permit and visa were cut and I can't do a visa run due to COVID-19?

Extend for seven days. 1.9k baht

You go to the immigration office and apply for a new extension, which will be denied, and then you get the 7 day extension denied stamp for 1900baht that gives you a week to get out of thailand

AND

during that week you get a hold of your consulate and get the "unable to travel due to covid-19" letter so you can go and apply for the emergency extension

and were you on the original 90 day entry from the VISA or were you on an extension from the immigration office?
