Recieved a Letter from Court notifying me there is a claim against me from Civil Enforcement (A parking firm)

So, on June i parked in a site managed by Civil Enforcement.

I booked from 7am to to 7.30pm based on looking back at the booking.

In november i recoved a letter from them saying i hadnt paid a PCN and that i needed to pay 170 quid and there was no email or telephone number to contact, i looked online and found no contact details for them and to be honest it had not details other tham the date and my car reg so nothing to state what was actually wrong.

I never recieved a PCN and at the time i was really busy with work basically doing 65+ hours a week for several months so i never did their process (hand write a letter and post it back) but to be honest i figured as i had paid anyeay it was unlikely to be a real thing...

Today i have receive a court latter saying there is a claim against me, its not a ccj or anything lkke that but i guess it could trun into one.

Its now 220 quid to pay, and it came with more info, which is that I arrived at 8.10 and left at 9pm. So it seems i did overstay my welcome having arrived a little late.

Is there any point in me fighting this is anyway, totally understand mistakes have been made on my part but i never received a PCN and my address has been fixed the entire time... so if i'm paying i would understand the need to pay the original fine + fees but this seems a bit much.

No issue sucking up and paying if that is the best option.
