Can we refrain from speculation please. It is of no benefit to anyone.
If the OP told porkies in order to garner sympathy then the advice will not be appropriate and the OP will ultimately be the one who loses out, so I don't think it is in anyone's interest to be telling lies and making up excuses here.
We can all make personal choices whether to help, or otherwise. This section exists in order to help people and offer advice. Playing devil's advocate is fine, speculation best not.
While I have no reason to doubt anything you said as I mentioned before, I think Fahad did bring up a quite significant inconsistency which may harm your defence. Perhaps your wife's memory is a little vague regarding exactly what happened, or that she may have got a few things mixed up, but I am in agreement with Fahad on the point that there is no way a Woking - Addlestone paper season ticket and a Zones 1-2 Travelcard season stored on Oyster could have been issued in the same transaction from the same ticket office if she bought it at Woking or Waterloo, as only National Rail ticket offices sell the former but they don't sell the latter. Ticket machines at Waterloo can sell weekly versions of the latter, together with London Underground ticket offices, but neither would be able to sell the former. Therefore there is simply no way these two products would have been issued in the same transaction.
Ignoring what intentions others had for doubting your story, I think it is important that you are absolutely certain about the things you claim. If you are not, then don't claim it, otherwise it could do more damage for your case.
If this is her first infringement, there is a good chance a large settlement would be accepted, if the right attitude is shown, but of course there is no guarantee. As I mentioned before, it is very unfortunately the way things have turned out, but it is not the end of the world.
