My Mother called to order a comfy cushion for a friend.They start off asking if you plan to make a purchase then ask for your Credit Card number.
That way they have you no matter what. No matter how often she said "NO" to the prompts they took it as a Yes. By the time the order ended she had multiple cushions, a roast pan or two and who knows what else. There was no going back and no one to speak to to cancel the order.
She called her bank closed the card and now has to get another card.
