How does Sberbank share your personal information?

I gave my friend a number of my card so that he could transfer money to me.
A friend made a translation and received a receipt.
My passport data appeared on his receipt (see scan of receipt under the cut).

I reported a problem on the page www.facebook.com/sberbank , I received a recommendation to write to zabota@sberbank.ru

On September 17, I sent a description of the story and the question to this address:
')

“Please let me know why and how my passport data appeared in the receipt and, thus, did my personal data transfer to a third party?”

It took almost 2 weeks, I have not received any response, so I start posting open messages.

I believe that it is important that the maximum number of clients of Sberbank learn about how the bank relates to their personal data.

UPDATE - NB: And in the Alpha-click of Alfa-Bank, you can find out the name and number of the client’s account, knowing only the email or phone number (open the printed form after the transfer). Walk, Rassay!

UPDATE - Sberbank: A bank employee reported that this was both an operator error and an error in the software:

beskov, as promised, come back with the results. Already we can say that your review has been very useful for Sberbank. As a result of a thorough analysis of this case, we were able to identify not only the error of the operator, but also a software defect, the elimination of which would prevent the possibility of such cases. So let me thank you once again for the signal.
