They've 'fined' me 3 times in the last 7 weeks. Each time I've provided proof I paid the charge as I have the emailed receipt. Each time they've written back saying it was an admin error.
4th one arrived today. Again I've paid the charge at the time and have a receipt. Do I have to tell them again (at the cost of a stamp to me, it's not free post).
Yes, I can afford the stamp but it's the principle of it. I've only gone over the 4 times (return) so it's every time I've used it meaning it's cost me an extra £0.56 for the stamp each time.
What happens if I don't write to them?
