Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello
Chat support and forum support are two separate platforms and they don't work with each other, so there's no way for anyone here in the community to connect you with whoever you were chatting with.
You can use the following method to get to them again, may not be the same person though. Go to https://support.microsoft.com/contactus, Type "Billing" and press Enter. On the next screen, click "Contact support" at the bottom of the page, then choose "Microsoft 365" > "Manage my subscription". You’ll then see the option to chat with a Microsoft support agent who has access to your account to help review the issue.
However, if you don't require remote assistance, i am happy to see if I can help you as well, if I know what issue you need help with.
