Dear sir/madam,
Your train company has provided an excellent service to me in the past. The trains have run to time, the quality of comfort is excellent and the staff have almost always been pleasant. In the past I would always have been willing to recommend your travelling on your services to London.
Last time I travelled I took advance of the very well priced <insert name here> special offer. Unfortunately, I forgot to take the required voucher with me on the return journey, leading to me being issued £111 unpaid fare notice. I attach a photocopy of the notice, which I have since duly paid.
I realise that since the terms of conditions clearly state that a voucher is required, am entirely to blame for the excess payment. I'm sure you can agree, however, that such a mistake is easily made. Unfortunately, the hardship incurred as a result of my mistake has prevented me from considering travelling on your services again, nor recommending your services to friends and family.
In light of the fact that I travelled in good faith and made an honest mistake, I would like to ask you if you feel it might be reasonable to reimburse me the extra costs, or the difference between an off-peak single valid on the train and the anytime single I was charged.
I thank you very much for any assistance you can give me, and I look forward to hearing from you.
Yours sincerely,
...
