Parking eye- letter before county court claim

I received a letter on 16th August saying I had stayed over the 2 hour limit in a local supermarket carpark by 43 minutes and as such I should pay £85 within 14 days. I ignored this as my son had received a similar thing a couple of years ago and was advised to ignore it and hadn't paid. I then received a second letter on 25th August saying the amount of £85 was now due. I again agnored it! On the 19th September I received a letter stating that as I had'nt paid "The requirements of the Protection of Freedoms Act required for keeper liability had now been satisfied" and that "in accordance with schedule 4 Parking Eye now has the right to recover any unpaid part of the Parking charge". I again ignored it because various forums suggested it was not enforceable. I have now received a "LETTER BEFORE COUNTY COURT CLAIM" which says I am in breach of the terms and conditions at Morrisons, Clevedon. The charge is therefore levied for breac of contract, because Schedule 4 of the Protection of Freedoms Act 2012 required for Keeper Liability had been satisfied. I AM NOW PANICING LIKE MAD CAN YOU PLEASE HELP, SHOULD I PAY, Very Many thanks for any advise you can offer xx
