I see you are new to this Forum, Alin, so I suggest that you read as much as possible on this thread and on the 'NEG Propaganda' and the 'Surgeries charge more for calling' threads: you will then see that it is very difficult to find out geo numbers for surgeries that have gone 0844 and that it is intensely frustrating to many other people.
If you really want to find the number, and help with this cause generally, I suggest that you look at how one or two people have discovered the secret number for their doc and try their techniques or invent a technique of your own. Also, you should write to the surgery and make a formal complaint, write and complain to your PCT, your MP, your local press and the Secretary of State, Alan Johnson. If you can, post details on this thread of what you have done and any replies you get. Also please sign, and get everyone you know to sign, the Petition on the PMs website against doctors using 0844/5 : ---
