Got VAC- Banned

Well, i used two different Bunny Hoppers. 1st the one from Steve Andrew and then
one which i could use "forever" without getting vac. I dont know which one of these got me banned.
I dont have any hacks on my PC (besides like a fov changer for MW2 but its allowed...)

Does any one have an idea how i got banned ?

Both hacks were on "release" and nobody before me said that he had been banned...

Also i have items worth like 700 USD on my acc and cant trade them obv. Is there any way to get them back ?
Like passing steam guard or with any trick ?

Would love to have answers

Sry for my bad english

no. you've been banned. you have lost all your money. Well done!
