Despite leaving BT I have actually had a great service on the forums. Personally I believe this is a helpful place compared to ringing India.
Due to my experience of lies with BT (on phone) why don't they get rid of call centres all together and make use of email services. Obviously no call back (which I one of the biggest issues where nobody rings back) and everything can be documented as proof to protect customers and BT.
Instead of call centres, virtual assistance lets have an email service xD or extend this forums to technical people.
This will be a cost effective services compared to phone calls. Obviously a small call centre will be needed for people with no internet at all.
