I am occasionally asked by clients (solicitors) for the phone numbers of service providers legal liaison officers, i.e. the department to contact for the legal acquisition of call records. I normally just advise them to search the internet. However, I have recently had purpose to find these numbers myself and the difficulty in finding someone within Orange or 3 etc who has any clue in who to put me through to is unbelievable. Does anyone have a list of contacts for the UK service providers legal teams? This would be very appreciated and could save me days in research.
