Free Traffic Legal Advice

I am seeking assistance and guidance regarding parking charges that have been issued incorrectly. Despite being informed that my vehicle was added to the permit list, as evidenced by a screenshot of an email confirmation, I have received over 15 parking charges totalling over £3,000. These charges were sent to my old address, unbeknownst to me until they reached the debt collector.
This situation has become incredibly stressful, and I am unsure of what steps to take next. Any assistance would be greatly appreciated
