I'm kept in a kind of vicious circle. Long time ago I was taking part in the Windows Insider Program using two Microsoft accounts (ID1 and ID2). I left the programs for both accounts using the appropriate link and I closed both accounts. But I'm keeping emails from Windows Insider Program. I had long discussions with Microsoft Support - they regretted that they couldn't help me. Now tell me please how I can ask to stop this everlasting SPAM? I cannot leave the program because I already left it and I cannot login using the proposed link because the Microsoft account doesn't exist any more.
The fact that even Microsft Support is refusing to help me makes me really angry. There is no way to get in front of the desk of the spam originator and to tell him to stop it. Is this really true?
