Today I got back home and had the joy of finding some correspondence from the South West Trains Prosecution Department. The letter, I think relates to a time when I found out that I did not have the cash on me to buy a ticket but needed to get to work. I intended to buy a ticket and had the money to do so but I just didn't have it on me at the time, hence I could not pay any of the penalty fare either. (Now with the sob story over I will continue with my question.) Anyway in the letter there is an issue, firstly the date referred to as the "incident date" is not correct, not by a long shot and so the letter effectively refers to an incident that did not occur. Furthermore there is no reference to me having not payed a fare, it simply states to someone who gave my name and address having been questioned by a member of rail staff about an incident that occurred on their property. Had the letter that came through had the correct details I would have no option but to answer honestly and directly, however the details that they have provided means that the honest response is that I was not even close to their property on the date of the incident stated in the letter. So my Question is:: Do I have any obligation to correct the mistakes they have made on their correspondance? If am not obliged to do so, should I answer honestly that I was not involved in any incidents on the date that they mention? Do I risk a higher fine/ legal ramifications should they correct their mistake at a later date? Am i better of not responding at all and letting this incorrect date go to caught where the case would be invalid? Any replies will be greatly appreciated as I only have 2 weeks to respond.
