Parking Eye issued a "fine"

[Niall]

Incorrect Ginge. Since mid last year i think it was, They do have the power to demand to know the driver of the car but thats as far as it goes.

I would write back ignoring that bit but more picking up on the fact they haven't provided you with any of the evidence you asked for and unless the next correspondence from them contains all the evidence you requested in full, you request that they no longer contact you again otherwise this will be classed as harassment and you will start charging them for your time to deal with the matter.
