I have recently sent off for a magazine subscription. I filled in the form in the magazine and sent a cheque for the amount quoted as printed on the form. A message has been left on my phone telling me that they made a printing error for the amount that I should have paid. They have told me that I could have a refund or instead have fewer magazines for the amount of money that I sent (the subscription should have been more). How do I stand? Do I have to accept what they have offered, or do I stick to what they printed in the magazine. Much appreciate any help.
