Back in october last yr i got caught on the toll bridge by Wales doing 65 in a 50, now i was still on the motorway but as you get to the bridge it's limited to 50

They sent me a letter a month later in november stating that ive been caught and wanted to verify who the driver was, i sent them back a reply immediatly along with a grovolling letter stating i have had a clean licence since day one and that ive never been caught speeding before and due to the nature of my job, would like to escape the points and be placed on one of those driving courses?
So that got sent of and another month goes by and they reply stating they have recieved my info and will look into it
Now this morning i recieved the letter saying they thought about my letter and in this situation are not prepared to do this and are going to give me the points along with 60£ fine.
This has really pissed me off cos ive been waiting 4 months to tell me this and think they've taken the piss

Now is there any way in getting them back ie asking for photo prove that i was speeding/prove there camera was calibrated and set to the exact mph etc etc and holding the situation up anymore as they,ve left me daggling for the last few months.....tosser
Any help would be appreciated
