BT Customer Service is the Pits

Last week I signed up with BT Fon so that I can use my laptop anywhere.
As we are signed up with Option 3 this service is free and unlimited.
This would be great if I could actually use it.

Today I tried to connect to BT Fon and found my E Mail Address rejected.
Despite the fact I received a confirmation message from BT Fon to that email address which is our primary email address.
I called the BT Fon helpline who insisted it was a problem they were unable to help with.
To cut a long story short I was passed through 5 different dept's, eventually ending up back where I started, the BT Fon Helpline.
Once again some guy called Chris who I'd already spoken to, informed me he was unable to help.
I slammed the phone down in disgust and lodged a complaint with BT.
I eagerly await a response.
