LONDON (AP) — Nationwide Building Society said Thursday that human error at the company caused more than 704,000 British debit card customers to have payments taken from their accounts twice, while technical issues hit customers of RBS Group-owned National Westminster Bank for the second time in just over a month.
Nationwide said that a human error saw debit card transactions made on Wednesday processed that day and again on Thursday, affecting 704,426 accounts. It said the issue was identified Thursday and will be corrected overnight.
Nationwide apologized to customers for what it described as a "one-off incident" and assured them any costs related to the error will be reimbursed in full.
Separately, RBS Group — which owns NatWest and Royal Bank of Scotland — said some of its customers experienced technical difficulties with online banking and debit cards. It did not specify what caused the issue, but said late Thursday that operations had returned to normal.
Last month, a weeklong glitch delayed the posting of credits and debits to millions of NatWest and Royal Bank of Scotland customers.
RBS said at the time a failed software upgrade caused the issues.
Hundreds of branches were forced to open early and close late in a bid to placate customers, who complained of bills and salaries going unpaid and delays in closing home purchases because money was not being credited to accounts.
