Thank you @ericsbrother, what exactly should I write to them?
I am really worried cause on the same circumstances but on behalf of Parking Eye,
Debt Recover Plus was able to grant a court order which I have disregarded cause I still thought it was just some other form of threatening from them,
and now I am left with a CCJ on my files which has totally disrupted my credit scoring.
I then paid the £165 fine through court but the CCJ obviously remains for 6 years...
