Cosidering the fact, that he never was banned before - though you've got 5 bans on your list (...?!), i come to the conclusion that appearantly you're not that innocent yourself.
A person who never got banned for teamkilling - well never got banned AT ALL - does not fly into a frenzy out of thin air. Something happened there, that i can't reconstruct.
He accused u of the exact same thing - and your screen prove that as much as they prove him teamhitting you.
That's why i won't - but let you - decide, what's going to happen next:
1) U forget about your request and play the game.
2) I ban you for 2 days (sixth !!!! ban, reason: teamwounding) and him for 1 day (first ban, reason: teamkilling)
you decide if it's worth it.
On a side note: people living in glass houses should not throw stones.
