That's strange, my experience with GitHub and GH Copilot have been great, unlike with other Microsoft products that have their billing integrated in the Microsoft account or MS365, or Entra or whatever they call the "company accounts" today.
Plus for 10$ a month (~8.50 EUR last month) I get more-than-enough-for-me access to Gemini, Claude and OpenAI models from my code editor. I wouldn't pay double for Claude Code or Cursor, so I feel like it's a good enough deal.

Copilot doesn't run on Microsoft's own LLMs, they're all third party. ChatGPT in office copilot, in github you can choose various other ones too.
Microsoft is really just a reseller there.
Personally I think Claude Code (with Opus in particular) is far better. Unfortunately they are very aware of this and thus it is eyewateringly expensive.
Put the LLM on answering (or at least triaging) your support tickets faster.
