Right after I contacted Microsoft the second time through the so called technical support contact form, I got a reply from someone who told me, he had initiated the termination of my Live OnceCare Abonnement and I shall wait a few days until I get a notification about the request call being finalized.

Half an hour later, I got another email from some other person who asked me to call a toll free number to quit the account myself: +49 (800) 1827615. However. I waited patiently another day or so and finally got a reply from yet another person who told me the account was successfully quit. So I got finally rid of Live OneCare. Yay!

To sum it up, here is the ultimative solution for everyone who’s trying to quit their Microsoft Windows Live OneCare Abonnement: Either call the toll-free number from above (if you live in Germany) or really try contacting technical support by stepping through Microsofts weird webforms. One hint though: Let them know that you won’t pay for any calls and that you won’t accept any forwarding whatsoever. They are supposed to fix that. Not you.
