Developing nanosatellite to be launched with foreign company.
The ICD (Interface Control Document, basically guidelines regarding design) is clear, but there are some key points we needed to ask with the launcher.

I've sent email to ask them regarding those questions

Then got a reply saying that it'll be forwarded to the engineering team.

That's it. 2 weeks in, no reply. Tried emailing them again to nudge them, no reply, resent the email the following week.
Still waiting till today.

Please reply me 😂😂😂
