My neighbour, a blue badge holder, received a parking fine for staying 2hours 13 minutes. She asked for my help as she was trying to pay it by telephone. Having seen this thread we went to Sainsbury's customer service just now. They couldn't have been more helpful. They explained that blue badge holders still get up to 3 hours free parking, but you have to go in and register your blue badge details with the customer services. They then also cancelled her parking ticket from last week. Big thanks to customer service staff and manger at Sainsbury's, Dog Kennel Hill! 👍
