Inability to Activate Windows 11 on a Parallels virtual PC once the Parallels licence is renewed.

I cannot activate Windows 11 on my Parallels VM - I get an error saying that the licence is in use on another machine. I have recently renewed my Parallels Licence. There is no part of the technical support pages or systems which now gives you access to a live technical support agent and Parallels support (after about 4 hours of trying to support me at great cost on my mobile phone account) now tell me that the only way to link my Parallels machine once again to the Windows account is to ask Microsoft to unlink the VM identity from my Windows Product Key so that it can be reconnected.

I would like a live support agent telephone contact number (0800 026 0329 in the UK is an automated call handling system which cuts you off if you have anything more than an FAQ enquiry). Microsoft used to have a "Call Me Back" option if one dug deep enough but that appears to have been taken away.

MORE particularly I would like email contact from Microsoft which can help me to activate my completely legal Microsoft Windows 11 licence on my virtual machine. OR Microsoft should issue a notification (particularly to Parallels users) saying that it no longer supports Parallels and removing the licence to use Windows with Parallels virtualisation.
