Don't pay. These guys tried to take me to court for £2.80. If you have the proof of purchase, let them take it further if they want. These guys make it especially awkward to get in contact, and when you do, they refuse your appeal even when you have all the tickets/ proof etc. They're just out to fleece the public. The letters are just stock stuff, and they rely on frightening 9/10 people into paying up. Easy money, at the cost of other people's worry and bank balance. I just ignored the letters in the end, after sending them a final letter TELLING them to take me to court! ****!

If you have the proof of payment, then let them take you to court. The costs will outweigh the ticket price and I'll bet they drop it. You've sent the proof. They have your money. What judge would rule against?
