Hiw long will icloud keep my stuff after not paying?

Fisrt of all sorry if this is confusing English is not my fist language. Ok So i just got a pop up on my Iphone saying that its time to pay for my icloud and the way i pay usually is by buying a itunes gift card to top up my account and i use that money to pay for icloud and now i'm out of the country and won't be able to pay for it for another week do you think they will downgrade my i cloud and erase my stuff?

If you stop paying for the storage you should assume your files will be gone the moment it can't be renewed.

There may be tolerance time before this happens, but since no time frame is given by Apple there should be no expectation of it.
