P.S. Sorry, I meant to ask for your contact's details if possible please.

I have exactly your problem. My Oyster card did not record my touching the reader and I was assumed to be a deliberate offender, with no possibility of any mechanical error. I had no idea that the decision about a Penalty Charge Notice or prosecution rests with the inspector who stopped me. Like you I have been a regular user of public transport over many years, and have never had any trouble let alone a criminal record before. I would very much like to try to bother TfL before I am due to appear in court, and am astonished to be in this position.
