Я что-то не понял, на форум пробрался агент Плимуса и удаляет мои сообщения?

Напишу опять: Плимус не дает сменить платежные реквизиты. Требует бумаги от банка с реквизитами.

Because it (настройка реквизитов в контрольной панели) was disabled for all of our merchants.
As a financial institution, we have to follow the Anti-Money Laundering regulations. This means verifying who the ultimate recipient of the funds is. This is why everything is going through our Risk Department now.

Please send us a void check or a signed letter from your bank to verify the new bank account details. We will then update your account's payment settings.
