Invalid I was unjustly accused...

i was accused for being a scammer and don't know why but i do alot of trading and would be grateful if you could put my steam rep to normal

Please read this thread on how to appeal scammer tags correctly: http://forums.steamrep.com/threads/howto-appeal-scammer-and-caution-reputation-tags.58/
You need to first appeal your scammer tag where it was first issued. In your case you need to go to Skial and appeal your tag there. Make sure you follow proper procedure there.
If your appeal there is accepted, you can ask to remove your scammer mark here.

but skial dont like me

That's doesn't change anything.

as in i already asked them and they said no and thats stupid and unfair

is that THE AcesGamer?
