Where do I submit documents for maternity leave? Do I need to go to a ZON or GCZVP? Online through hisv sent me an email that the account statement is not correctly indicated. I just made a screenshot with the data from the Caspian Bank and attached it. When I call the phone number in the letter, the fax is activated. On 1414 they said that hisv does not accept the account from the Caspian Bank, but only from the post office and folk. But many submit through hisv and indicate the account from the Caspian Bank. Or should I directly submit the account with a stamp from the bank, can you tell me who did this?
