Thousands of Nationwide building society customers were sent new debit cards that didn't work in a major bank blunder.
The issue affected people who were sent replacement debit cards for cards that are due to expire at the end of this month.
The replacement cards were posted on May 30 and May 31, meaning customers should have received them last week.
You can normally start using a replacement bank card straight away - but Nationwide admitted that these cards weren't activated until this week.
It means that customers who tried to use their new card last week found it didn't work.

The issue was first reported by MoneySavingExpert.
Now the cards are activated, you should be able to use them as normal. You could also continue to use your existing card until the end of June.
If your replacement card still isn’t working, you should be able to visit a Nationwide branch where they will manually activate it for you.

Nationwide separately told The Mirror that the problem affected a "single batch" of replacement cards.
The error didn't affect new cards that were sent out in replacement for stolen cards.
In more banking news, some 112,000 customers of NatWest discovered they had been debited twice as a result of a payment glitch at the bank last month.
Some accounts were showing a lower available balance than normal as a result, with some users complaining that the error put them in their overdraft.
A message on the NatWest app read at the time: “Some customer accounts are showing debit card purchases twice, and in certain cases their available balance will be lower than it should.
“We’re really sorry for any inconvenience.”
