For the first time in all the months of this scheme, I did not have a card in today's Mail on Sunday. I've just phoned up and they gave me a number and I don't think I was on the phone for even a minute so not a costly call.
From what people have said on here, I was expecting it to be a long call especially when they began to give out different numbers for different options. But No.1 was for missing a unique card and as soon as I pressed it, someone answered. He asked for the advert, gave me the number - perhaps 30 seconds in all. So a 5p. call for me.
