Ok confirmed that he is using live: annov_7_1 . Can you add a screenshot where it makes other see that it is invalid. I don't have that office version to check.
Archive of user using the same live Id :

I already gave him valid serial number. But he claimed that the keys didn't works. I gave you second key, but you claimed the same.
It is you who blocked me, not I blocked you on Skype.
