Thanks for your post and welcome back!
Sorry that you're having problems managing your Parental Controls. This isn't something the Community would be able to help with so you can send us over your details and we'll give you hand to sort this out from here.
I have sent you a private message with instructions on how you can send us over your details and we'll look into this for you. See: Private messages
My colleagues in the Parental Control team have been investigating the issue. They've asked if you could try activating the service again?
Please could you give that a go and let me know how you get on?
Thank you for taking the time to post back. I'm pleased the Parental Controls are working for you.
Please accept my apology once again for the delay in getting this fixed.
