You're quite right, the contact centre is only open 9-2 on a Saturday, and closed on Sundays, but we always have a member of the Social team on Facebook and Twitter that could help. If you haven't got this sorted yet, please call the Customer Care Team on 0330 102 7517 so they can get this sorted.
I'd recommend they have a look into the Priority Services Register (PSR), which allows our vulnerable customers to request for additional services that may help them with their energy supply.
Finally, I'd definitely recommend smart meters, as not only do they have a non-disconnect period over the weekend, they also make topping up much easier. You can get one booked in here.
