Arrgh that's a bummer mate, I thought 2 accounts would be ok. Have they flatout refused you and lost your money? Or have they asked you to get back to them with what they need?
I just gave them a call and the woman said it would be fine to just send copy of bank balance. She was really chilled and seemed like it didn't even matter. Still not totally convinced but i guess it's fine.
I can only print out the balance for each month as I don't have a statement for non active months. Do you think the balance with a official stamp will be ok?
