As a technical school in the Netherlands we ordered and paid for two Mini Breeze generators. The order and payment by credit card was done 0n the 17th of November 2009.
Until today the seller did not send anything and is unwilling to do so. We did our complain at Google Checkout Support and we got the following answer:

The funds will automatically be returned to the credit/debit card used at the time of purchase.

Our specialists should complete your refund within seven business days, and refunds can take up to an additional three business days to appear on your credit card statement. If the refund does not appear, please contact your bank for more information. If your card is now closed, please contact your card-issuing bank about forwarding the funds to your new account or issuing you a check for the amount of the refund.

If our specialists are not able to complete your refund, we will contact you. If the refund is successful and the seller provides sufficient evidence that your order was completed according to our Terms of Service and their published policies, you may be recharged for this order. If you don’t hear from us within four weeks, please consider this refund final.

We sincerely apologize for any inconvenience this order may have caused you.
