You have claimed I have parked somewhere I haven't. You are harassing me with letters increasing my fine. The only number you have provided is an automated one to pay the fine I should not pay. So where do i go from here? I want photographic evidence that I was apparently parked there as my car has not been cloned nor has anyone else used and parked my car. I have been to the police who believe this is fraud (I have a reference number back from February). This is a disgusting company which seems to be a scam.
