What should I do if my cooking school can't provide the official acceptance letter for my DTV visa application in Malaysia?

Hi guys, looking for some advice. I applied for a DTV (Soft Power – cooking class) visa through the Royal Thai Embassy in Kuala Lumpur (I’m Malaysian and was back for other errands). The embassy got back this morning and approved all my documents except the acceptance letter from my cooking school, stating that it must be an *official acceptance letter issued by the Thai government*.

I contacted my cooking school, but they said they are a private institution (so are other cooking schools?) and can only provide standard documents (payment receipt, enrollment confirmation, school profile, registration certificate, owner’s ID, etc.). At this point, they’ve already enrolled several DTV students, presumably approved through other embassies. This requirement didn’t seem to exist before, so I’m wondering if it’s a new or embassy-specific rule.

What would you suggest I do in this case? I’d prefer not to reapply through another embassy if this is now a general requirement, especially given the high visa fee. Has anyone faced a similar situation?
