Thank you.
So you have said that you identified the driver, but nowhere in that text do you identify the driver. Have you sent anything else? If no, why do you think you've identified the driver?
Is there any evidence on the appeals portal beyond what is shown on the NtK?

Regardless of what happened in that other case, you shouldn't be surprised to have a different outcome. Operators rarely apply much logic to anything they do.
The advice of this forum is typically to not bother with the IAS stage since they only accept around 4% of appeals, however you could if you wanted to, or you could follow up your appeal to the operator with a formal complaint. It's likely to be a waste of time.
Aside from that, move on with your life, expect some debt collector letters which you should ignore. If you receive a Letter of Claim or a Claim Form from the courts, come back here. In the unlikely event it goes to court it should be easy to defend.
