is that correct english?
doesnt fit to me, surely its
This is out of control
this has became out of control.
but then on google I see for headlines
"
Why banking got out of control in the digital age"
where I'd have thought
Why banking is out of control in the digital age
why banking became out of control in the digital age.
or even
why banking has become out of control in the digital age
sounds much better??
this has got out of control sounds really chav uneducated pleb like to me
You are right, I am sure that when we were taught english language at O level, words like got were discouraged. Your first phrase is concise and sounds correct.

Esp "got". There are so many better replacements: received, attained, acquired, etc.
