"Dealing with multiple appeals and a court claim" are not arduous when following the advice given here. At most they involve posting a question about the process and next steps and receiving the necessary advice on how to proceed, which invariably, involves a few minutes work, copying and pasting the recommended text into an email and send it.
Dealing with the letters that arrive, again, are not difficult to deal with. Any useless debt recovery letters can be safely ignored, shredded and used as hamster bedding for anyone cares. The only letters that must be responded to are any from HMCTS regarding a court claim. Even a Letter of Claim (LoC) from a bulk litigation company does not have to be responded to, although we do advise that they should be, and again, we provide the content of the email response.
As this is a (not so) Smart Parking PCN (assuming it is even issued), as long as the advice is followed and a few minutes of reading the advice and acting on it once every few months until this concludes, is not exactly an effort. It is all a matter of emotion and, if treated correctly, a great life learning experience and education on how to stand up for your rights.
