NCP parking fine help

[KINGER1]

The story is My husband and I entered an Ncp car park n Lyme Regis in August last year at approx 8.15 pm. It was dark and my young son was asleep in the car. I jumped out and went into the local Tescos whilst my husband circled the car park. We can have been in there 13 mins and then left. Several weeks later I received a PCN from NCP. Firstly I don't live locally and visit this area maybe 1 a year and I did not even realise it was an NCP car park. It was dark so made a mistake. I am not one for not paying for a ticket. Just didn't think as it was late. Anyway I have done nothing and have subsequently received a further letter from NCP increasing the charge to 160 pounds then letters from Trace recovery. And a letter from BW legal and now a letter of claim giving me 30 days to pay with information sheet stating even more costs. What do I do now please . D I still ignore or will they take me to
