Ulster Bank has said the majority of its systems are now showing customer account balances for today?s date.
A technical failure, which has been condemned as unacceptable by the Central Bank, has left nearly 600,000 customers without access to funds for nearly three weeks.
The bank said yesterday this coming week would be the final week of any significant delays for customers.
At 1.30pm today, the bank said that in the Republic, the majority of its systems were showing account balances for Monday July 9th.
But there were still payments remaining which had yet to be reflected in account balances.
It said some transactions may not yet be either debited or credited and that the order of transactions on its Anytime Banking system may not be in the normal date order.
?All affected accounts will continue to be updated as we work through this backlog of payments,? the bank said on its website.
Debit cards will work depending on the balance on the customer?s account. However, balance and transaction lists may not reflect point-of-sale transactions.
Ulster Bank said credit cards were ?fully functional? and it would waive the cash advance fee and interest for Ulster Bank credit card holders who use their credit card to access cash during the current incident.
?As we work to restore normal service some customers may have experienced duplicate entries appearing on Bankline. This issue has now been fixed and any duplicate postings have been reversed. All entries will include narrative referencing the reversal to the original transaction,? the bank said.
Its ATM network is ?fully available? but may not show correct balances.
Services on Anytime internet and mobile banking are available for viewing, making transfers and payments, but customer balances and statements may not be up to date.
Extended branch opening hours will continue in 51 branches from 9.30am to 7pm today and tomorrow. A further update will be issued tomorrow on opening hours from Wednesday to Sunday.
The bank said an online webchat service was available to assist customers and it also has a Twitter account at @ulsterbank_help.
More than double the normal number of staff is available in call centres and some 2,000 calls were handled yesterday.
The telephone helpdesk in the Republic is open from 8am to 10pm on 1800 205100. Those calling from abroad should ring 353 9156 2910.
