From whom Google took money, and then did not admit it? //Developer Program?

Question

Google

I register for participation in the Google Developer Program: transactions go through, the money on the account is blocked, and Google at the last moment says that I'm sorry, "the operation was canceled" Therefore,

2 questions:
1. Who had this? How did you fight?
2. Is there an adequate way of Google technical support, where the issue can be resolved?
PS I paid 2 times from different cards (visa \ mastercard), both in dollars and are great for any operations.

Answer 1

It happens sometimes when money is blocked, but then the bank does not transfer it further for some reason. Usually, after a while, the money will be unlocked.
The best thing is to ask the bank for more details.

Answer 2

It was when buying a Nexus 7. Surprisingly, the transaction disappeared from the statement.
