Okay thanks! im wondering if there is a chance however that they’ve lost the file and therefore if I call them up will that not mean they reopen it again?

Hi there I was caught speeding doing a 76 in a 50 (bad , I know) The offence was 4 months ago. I sent of the NIP saying I was the driver but have not heard back since I don’t have proof however that I sent it off Does anyone have any advice on what to do?
