In the process of renewing myself. Apparently not only do you have to maintain the 800,000, but it has to be in the same original account.
I have two accounts, one for my daily transactions, one for my visa obligations.
They don’t like the one with no movement for some reason, despite dropping 1000 day of, and having bank certificates. No, they act confused and mystified until I show my other bank book. Happy then, they forbad me to allow THAT account to drop below 800,000. *sigh*
I tried again to let them use the visa account, but they said that was not the account on record.
