I have had problems with Clubcard points a couple of times. The first time, I had every receipt. I buy things for people at work every weekday, and over a period of time the points on the statement didn't add up. I was missing over 100 points. When I queried it with customer services, they eventually accepted that I was right, but still didn't adjust my balance. I then wrote to Tesco with a copy of their e-mail, admitting that my points were wrong. I never received a response, or had my missing points put on. Now, a year later, my wife has the same problem. She rarely uses her clubcard, but she keeps every receipt. Her receipt on 24th February showed a balance of 439 points, plus 12 earned on that visit. Her next receipt 4 days later showed just 314 points. When she complained to customer services, they claimed that the points had been converted, and sent out as coupons. But this wasn't true, as she had earlier received a quarterly statement telling her that she had insufficient points to be given any coupons for that quarter. We are now waiting for Tesco to investigate further, but I don't hold out much hope of her getting the points back.
