Hi @sojo
I had the exact same issue we were very freaked out. I was emailing Home Office, Visa Team, everyone. I even contacted immigration lawyers. In the end because the Bank statement is not required for a dependant visa according to the laws, we did not provide any bank statement. Her application was successful and she received the visa. But please don’t take this as an advice, it might have just worked in our case.
