I pre-ordered a camera with Nikon and after 2 months of waiting they cancelled my order. I received an email simply saying it was cancelled, giving no reason as to why. I had to take the time to call them just to figure out what happened. After a lot of back and forth, several contradicting messages, and far too much of my time wasted I figured out what happened:
When we placed the order we gave them authorization to charge our credit card. When they were ready to ship the order 2 months later they attempted to do so, but so much time had passed that the authorization had expired. To be clear, my credit card was fine, it had plenty left on it's limit to make the purchase, but Nikon's authorization to charge the card had expired. Instead of contacting me to rectify the problem, THEIR problem, they simply cancelled the order, losing my place in a 2 month long line.
After discussing this with their support we were told that they could not give us our place in line back.
This is a $3,000 professional camera but their service is about on par with a shady 3rd party seller. In the end this experience made me change my mind and I decided to not purchase the camera.
