Tina Farrell, 23, from Manchester, called Camelot after failing to win with several cards.She told the Manchester Evening News: “On one of my cards it said I had to find temperatures lower than -8."
“The numbers I uncovered were -6 and -7 so I thought I had won, and so did the woman in the shop. But when she scanned the card the machine said I hadn’t."
“I phoned Camelot and they fobbed me off with some story that -6 is higher – not lower – than -8 but I’m not having it."
