Firstly, Thanks to anyone that takes the time to actually read this and help me
So about a month ago I received a fine on the DLR for an invalid ticket. I was travelling from Colchester Town to Devons Road. I got my ticket in the morning from the ticket machines at the station as there was a que at the ticket office and I didn't want to miss my train. I saw on the screen it said 'London zones 1 - 6' and Devons Road being Zone 2, I clicked on that and got a return, it cost me £45. As far as I was concerned this was the correct ticket and I had no reason to believe that this wasn't!
