I'm not sure if this thread is interested in shop.nokia.co.uk as well as nokia.com.

Fwiw, a number of us in the UK who ordered from shop.nokia.co.uk are getting the "credit card declined therefore your order has been cancelled" problem.

See thread "Nokia N900 - UK Release Related Information" if you're interested.

There are reports that people have to reorder, and at least one has been told they lose their preorder discount deals, which is upsetting as it can amount to a lot (30% in my case), as well as their place in the queue. However I cannot confirm those reports, as I read the "credit card declined" mail after the shop's telephone support closed for the day, at 5pm, so I will call them tomorrow.

It was so exciting, too, to get the "your order is ready to be shipped" mail, then 40 minutes later, "your order has been cancelled".

My credit card company could not give me a specific reason for the decline, only that they put a block on the card for fraud prevention. The block persisted to prevent future transactions, until I called the card company. Everyone who has had their transaction declined and queried the card company reports the same thing: Fraud prevention.

A most intriguing thing is the card company said they have logged a declined authorization, but a short time later logged an accepted authorization for the same amount. They told me acceptances are sometimes lost, though, so not to count on it.

Could it be that shop.nokia.co.uk's order handling has received a declined authorization, sent a "cancelled order" email, and then later received an acceptance and passed through the order anyway? Perhaps there are bugs remaining in the order handling process...

Or perhaps it retried in the normal way, and they have been logged in reverse order by the card company.

If it is Nokia's fault that these orders are being declined and cancelled, I think it would be reasonable to let customers have their previous discounted price, perhaps with a different card if there are persistent declinations happening as some here report.
