Hi @sndt83 welcome to the forum and thanks for posting. I've moved your post to create your own thread as that's the best thing to do.
Sorry that you are unable to claim your reward card. You should be able to claim your reward card the day after the cooling off period has passed. For example the 30 days on BT Mobile you will be able to claim on day 31. If your cooling off period has passed and you still cannot claim your reward card post back and let me know and we'll be happy to help you claim it.
