Can't Delete Apple ID From My 1st Gen Ipad Air

[Sylboy]

So i have a problem with my iPad air first gen.
I'm logged in on a Apple ID that doesn't even excist anymore, even when i try forgot password and i enter my Apple ID it also says it doesn't excists.
So the main problem is, i can't reset my iPad and i can't purchase any apps.

Does anyone know how to fix this? Maybe permanent delete is from my idevice

Translation of the picture above is: (email) is not an Apple ID

(Sorry for bad English)
(And maybe wrong topic :c)

However there may be nothing you can do but factry reset the iPad and reintegrate it with iTunes. best bet, call Apple, though if ou're out of warranty, they will be of limited help to you

I already did factory reset the Ipad, but i need to activate it and that's the tricky part. I need to have the password but the Apple ID doesn't even excists
