According to Citizens Advice:
"If you have a contract, the company can’t usually cancel your order, even if they realise they’ve sold you something at the wrong price. They’ll only be able to cancel it if it was a genuine and honest mistake on their part that you should’ve noticed."
I believe both Mr. Tommo and Mr. Sam
HAD a contract...
Trading Standards may be somewhat interested.
