, that is the same thing as saying your visa is still valid, as it has been extended, and from what you say about the embassy there, go apply for your COE, as long as you have met all the requirements, like covid-19 insurance, quarantine hotel ready to be booked, etc. It works best to physically go to the embassy if they are not answering you. But, by all means apply, as you want to get back to Thailand, and out of quarantine before November 13th, so you can get your next extension rather than starting over.
