Well if the slip (ie. receipt!) said 2 tubes then they've clearly breached the sales contract.
I hope they send it to me to make up a duo )I have sent mine back.
I got an email just now;
Thank you for contacting QVC.

Can you believe it, I’ve looked on my account and on the list of orders it says Alpha-H Liquid Gold Smoothing & Perfecting Mask – not a duo, they seem to be wiping things out so the customer has no prove what they bought. I wonder if they will try to recall the emails of my order and dispatch and may be delete the order from my account.
