Welcome to the Community, @dekan
I've just moved your posts over to their own thread so everything is in one place.
As a first port of call, I'd recommend checking out our help page here which should let you know all the details you need on how to remove content lock.
Just be aware that if you're on pay as you go, you'll either need to give us a call and verify your age via a token credit card transaction, or visit one of our retail stores with a valid passport or UK driving licence.
