I rarely post here any more, but have a lot of experience in handling Delay Repay claims and suspicious travel and claim patterns are very easy to pick up on. TOCs use CRM systems where each claimant has their details logged so a history of complaints and claims can be seen. That's just as much for good customer service ("oh, this is the third time he's complained about this station's toilets, that's not good at all") as it is for anything else.
Everyone at the TOCs knows about the subscription services that show delayed trains, and everyone there knows a less lazy fraudster will even mine RealTimeTrains etc for delayed trains. People who work for TOCs have a good idea how many claims an average season ticket holder will make and people who make a large number of claims will stand out.
What's especially stupid about using tools like Delay Repay Sniper is you are not the only subscriber! Hundreds, or thousands of people get the same notifications for your route...and guess what? A lot of those will make the same claims as you do, meaning it's even easier to see the group of people who always manage to somehow take the most delayed train of the day.
Dodgy claims on their own aren't compelling court evidence, but consider how you'd answer these questions in a fraud trial (the details aren't particular, but I can well imagine the line of questioning) :
- You travel on your season ticket from say, Colchester to London. Why do you have a season ticket?
- Do you work in London?
- What do you do?
- What times do you normally work?
- Can you explain why you arrived in London two hours early on X date?
- You work from 9:30am until 6pm. Did you travel, as you claimed, back home from London at 12:30pm on X date?
- Do you use a subscription service to notify you of delayed trains?
- Do you ever submit claims for trains you didn't take?
- Do you ever submit claims for trains you're not sure you took?
- How many claims have you submitted over the course of your season ticket, and how much has been repaid to you?
- The Train Company suggests you and other claimants use this delay repay subscription tool to maximise the number of claims by claiming for delays which didn't affect you as you didn't travel on those trains. They have evidence that there were 65 such claims on the 3:15pm departure on X date from passengers who use this subscription service - but their passenger data shows there are usually only about 50 passengers aboard. I am sure you can see why the company finds this strange. With this in mind - and bearing that you told us you work until 6pm - are you sure you did in fact take that train?
The posters seeking help on this page well know that claiming for delayed trains you never actually took is dishonest. I suggest that Greater Anglia have reasonable suspicion to send out these letters and I don't think they would have done so lightly.
I very much recommend taking legal advice, as the offence of fraud is serious and will have lasting consequences. If you made dishonest or incorrect claims, I recommend trying to come to a settlement with the TOC using a solicitor.
