DONT DO THIS! been down the same route,£50 fine turned into £455!!!! bailiffs banging on the door,had lots of hassle but got it down to £100,that was a private firm too, appeal it in writing but if you lose just pay it,it aint worth the hassle even if your in the right,my princables nearly cost me £455 and caused me a headache.
Must have been a council ticket then, as a judge won't write out a court order for bailiffs given that they have no idea who the driver was. They've sent the letter to the registered keeper who is in no way legally bound to disclose who the driver was, and as such they have no one to claim against.
Husky, seriously mate, don't pay. And you can't pay in 5000 pennies either, as they don't have to accept it.
