Cancelled my order with Tesco Direct (£79 worth). They were fine about this, helpful and said as the order has not gone out, it's ok to cancel. My status on the online account says 'refunded' and I have recieved a refund to my credit card.
However, I used a 500 points voucher, which I have recieved an I have also recieved my whole order!
What would you do? I feel I should keep quiet!
