Got an email from Tesco today saying my order for Dan Brown's Inferno has been cancelled. Had pre-ordered this with a 500cc bonus... anyone else had the same?

"We work hard to make sure we have no problems with our deliveries, but in this case,we got it wrong."

The items affected are:
Inferno 1 £9.00
The total refund that will be processed for items affected is £10.75
