Hi Olly464,
Thanks for posting on our community forums. Sorry to hear that you're experiencing some issues trying to access certain websites due to the child safe option not being removed.
You advised you have already tried to remove this option yourself, did you try this by signing in to your online account and disable each level of protection? You can use the link here.
If you have already tried this and are no further along, we will certainly take a look at your account for you.
Please let us know, and we can pop you over a private message to take some details.
Kind regards Jodi.
