Booked a weekend camping for last May. Covid closed the campsite so they phoned and asked if I wanted a refund or the booking carried over to this year for the same weekend, same pitch, same price. I asked them to carry it over and they sent me an invoice and confirmation showing the price, balance etc, all paid.
I randomly logged in to the booking today on their website and the booking shows £4 outstanding. Phoned them up and asked why and they said prices have gone up this year. I explained to the lady on the phone that the booking was rolled over from last year and I was told it was the same price. I have an invoice showing balance as £0 etc and she didn't care and just kept saying prices have gone up. I know it's only £4 but it's the principle! Can they even legally do this?
