Ban Appeal - kind of a long story

About not sure how long has it been (maybe about 4 months ago or more), but I got banned because of excessive team killing. Far as I could remember I joked around with a guy and he didn't like it then he teamkilled me and reported me but nothing really went on, then we switched maps twice while my squad was being really active so we were more focused in the matches until my squadmates left and I ended up in his squad and he kinda left and took 3 people with him, the squad was not really focused and they scrambled. Later on, he neglected helping me since I was a downed medic then I respawned and killed him and his friend and got banned. I didn't care as much because I was not into videogames back at that time but today is one of the few things I can do. I acknowledge that I was wrong and I'm sorry about that. However I do know that he was no saint either.

I had no idea it had been 7 months, that's a lot of time...

I am not really sure wheter you got a decision in this, but it would be nice to know if it can get appealed or not.
Thank you,

To be honest this was the first time I messed up intentionally. The rest wasn't intentional...
But thanks for all.
