Ulster Bank, Bank of Ireland and AIB need to "get their act together" and fix their ATMs permanently, a retail group has warned.
David Fitzsimons, Chief Executive Officer from Retail Excellence Ireland has warned that the loss of ATM operations for Irish consumers had a "poor" effect on shopping.
He said this Christmas "most retailers will accept and be happy with parity", as footfall was down on the high street due to adverse weather and ATM problems.
Mr Fitzsimons said: "It's not good. We've got very discerning and somewhat cautious customer so anything that prohibits spending is bad so not being able to take cash out at ATMs was poor, it was a significant inconvenience."
"It led to lots of queues and suchlike so we're glad that it's fixed and it's a lesson for next year.
Allied Irish Bank (AIB) customers were unable to withdraw money from ATMs because they were mistakenly registered as being over their daily limit at the weekend.
Bank of Ireland customers also had problems on Friday.
Ulster Bank customers also experienced severe problems with debit and credit cards in early December.
