I don’t think it’s fraud on the DR side if you actually take the trains and intend to travel.
If you didn’t actually intend to travel, then claiming DR is fraud.
If you didn’t actually intend to travel, then claiming DR is fraud.
It would be better if the law was changed so that any transport company selling a ticket is forced to refund if they couldn't fulfil their obligation, regardless of whether the ticket was used or intended to be used. Can't provide the service? Then don't sell it!
There’s differences in consumer rights effectively between a refund and compensation (like DR)
Easiest example is if you have a season ticket, but you have the day off. You weren’t going to take the train to work that day, so no intent to travel. If you claim DR, then that’s fraud for the compensation.
