It might be a coincidence but I have just had a cold call from a place in London I walked past last weekend. I never answer cold calls so I'm afraid I don't know who it was or what they wanted. I blocked my number and tried to call them back to find out who they are. However I got the message "incorrect number". Tried on our landline also blocking our number but got "number not recognised". I am confident I called the number correctly. Went on UK number to search the number and they amazingly gave me the map co-ordinates and a google map showing where the call originated from. That is how I knew I had walked past the place. I haven't been in that part of London for maybe more than 10 years, so coincidence or not? This has happened at least once to my knowledge before from a shop I visited. Again, coincidence? I accept that the security services can do this for national security, (my wife once had to make a 999 call on her works number blocked mobile and the police knew who she was without asking) but I am not happy at all for commercial interests to have such control over my phone and who knows what info on it. Anybody know what may be going on?
