John you are forgetting that the driver picked up the person at the airport. Billions of cameras up there to find the lady, what taxi she got into and then the details from the taxi.
And it wasn’t the NTA that rang the driver, it’s was the Gardai, and they asked is it ok to pass on your number to the HSE.
Again you get the wrong end of the stick and run with it.
