Hi, I got one of these PCN issued to me on my wifes car. The only trouble is they are trying to recover the money from my wife and in fact they do not have a contract with her so after several letters they have backed down. As it is contract law and you need offer, acceptance and consideration to have a contract, the only problem for the parking agencies is that they cannot prove who they have acceptance with, as the car driver is not always the owner. So just ask them for proof of you being at the seen which they can't prove, they can only prove the car was there. bummer on them. Think i will go and park there a few more thime just to wind them up.. ha ha
