Maybe Google tried to charge you twice on the same day, or you have increased your inversion to the point that you daily spend more than your credit card allows you to.
It has happened to me many times. The solution: Talk with your bank to increase the limits on your credit cards.
Hopefully, Google tried to charge again a few minutes later instead of automatically suspending accounts. This is a good reason to have a backup card on file with Google. (Then again, if the payment processor is being flakey, the same problem may affect the second card as well.)
thanks for your comment. It seems that my case. On same day a expended five hundred on domains regs on moniker, it was accepted correctly. Also namecheap and even a paypal verification charge was on same day. Just Google charge was denied for a mistery reason.
Could it be too much similarity within the last succesfull charge and the failed one? I'm seeing there are only a few cents of difference!
