Contact support, I'm not Microsoft and I'm not responsible for other buyers actions. You guys took too many keys and invites are connected to each other. You should have bought an admin and you would be able to control all your invites.
Just take a look - no one with an admin has got any problem.
Anyway, all items sold.
Response from Micrososft.
Thank you for your patience in regards to the issue you have experienced concerning the usage of your Visual Studio Subscription benefits.
Your account does not satisfy Microsoft requirements, and will not be given access to this Visual Studio functionality.
Based on the above, I will allow myself to close your case for the time being.
Thank you and kind regards,
So, no solution,
waste of money, 0 claims keys.
