I'm now suddenly experiencing the same problem many others have. The parental controls have changed without my knowledge, and I cannot reset them due to technical error.
Did you manage to resolve your issue with Parental Controls? If not I'll be able to help, please send me in your details using the "Contact The Mods" link found in my profile.
In your profile I can see a 'Send a private message' link, but no Contact the Mods link.
I too have this problem - I cannot manage my Parental Controls due to a 'technical error. I have rung the BT and got through to the Indian call centre more times now than I wish to remember. I get promises of calls back and nothing gets resolved. Please can BT help and fix this problem?
