Hello GROBTIV,
Thanks for your post.
Sorry to hear about the issues you are having with our Fibre line and being unable to make calls to BT Numbers.
This is a new issue I haven't been made aware of.
What I would like to do is look into this in a bit more depth for you.
If you don't mind, I will need to send you a private message to pass security.
If you can check the purple envelope top right of your screen that would be great.
Regards
Gareth_L
