I travelled at the times stated on each ticket there is only ONE that was cancelled, there were no delays? I've posted the picture of what it said above that's the only train I was not able to get on.
As the train was cancelled and the return portion was unused, you can get a refund of
half the cost of the return ticket.
You need to be really clear with Raileasy what happened. A lot of the things you've posted are not relevant and not required information but we've struggled to obtain the information that is relevant.
Something like this should suffice:
"Dear Sir/Madam,
I write to you regarding booking ref <reference>.
Due to the cancellation of the <train details> train, I chose not to use the return portion of my <ticket details> ticket; instead I used alternative transport for this portion of my journey.
Therefore can you please issue a refund of <amount> which is the value of the unused return portion of this ticket.
Yours faithfully"
Next time, my advice would be to make the journey on the next available services (seek staff assistance) and claim delay compensation for the whole journey. In this case you would have probably* got £47.75 instead of £11.35, albeit at the expense of a delay.
If my arrival time is critical I generally book an earlier departure than I need, and accept the delay compensation, rather than incur additional expense in trying to avoid a delay, as this works out better, I find. But that's personal choice.
(* based on a 1 hour delay; in practice the actual delay may be longer or shorter than this depending on the arrangements in place and next available services)
