LONDON (AP) – A British banking group says it has almost fully cleared up a weeklong banking glitch which delayed posting credits and debits to millions of customers with its NatWest and Royal Bank of Scotland accounts.

RBS Group said Tuesday it had successfully updated all but 1 percent of NatWest and RBS account balances overnight, but that has not stopped a flood of criticism over the online banking mess.

Much of it was directed at the (at)NatWest Twitter account. Problem is, the owner of the account was not a bank but a 22-year-old teacher, according to British media.

The glitch has affected bail payments for court defendants, and many customers say they are worried about late payments on bills.
