Ok, this might take a while to explain, but any advice is appreciated. So, on Monday 3rd I was fined for not having a train ticket. The conductor said he would send a letter in the post as I did not have the money there and I have to pay within 14 days. Last Monday I sent Thameslink an email as I had not revived a letter. Now today, the last day post comes before I have to pay, still no letter. I called Thameslink customer service, who told me they could not help, and gave me the number for penalty fares (an independent company). They said they were just a payment line and told me to call Themeslink, so I call up Thameslink again and explain the situation. After being put on hold the lady said her manager said to call penalty fares again, so I do and am told they can't help. So I call up Thameslink and explain this (again), they say they can't help but would make a note. The woman from penalty fares said that the reference number from this slip of paper the conductor gave me wasn't on there system. But the conductor did leave a small note(?) she then hung up before I got a chance to ask further (she seemed quite moody in all our calls). What do I do? I'd quite like to pay this fine and not get prosecuted.
