The next document in the chain is the Order for Recovery, which you then challenge by making a witness statement to the Traffic Enforcement Centre, the full process is explained here:
https://www.trafficpenaltytribunal.gov.uk/charge-certificates-and-orders-for-recovery/The statutory ground that applies to you is "
Representations were made to the local authority or charging authority within 28 days of the NtO / PCN being received, but no Notice of Rejection (NoR) of Representations was received".
However you don't want to risk the Order for Recovery going missing in the post as well, so you need to keep an eye on the amount due on
https://ocmlive.xrxpsc.com/bristol/OCM-FE/OCM/Once the 14 day charge certificate period has expired, check the amount due at least once a week. As soon as it goes up to £198 or the status changes to "OFR Sent" or similar, you can download form TE9 and fill it in (no need to print, just type it out on your computer and save), remember you are not the "
applicant", the "
applicant" is the council.
Once that's done you can email it to tec@justice.gov.uk with the PCN number in the subject line and both the Order for Recovery and the Charge Certificate will be revoked.
The council will then refer the case to the Traffic Penalty Tribunal for the appeal to be decided on its merits.
Let me know if you'd like me to represent you at the tribunal.
