Commonwealth Bank has told customers who executed instant payment transfers last week to wait until today for the transactions to be completed.Delays in the processing of instant payments using the PayID-based Osko service were compounded by the meltdown of CBA's main banking platforms on Monday.However, the system outage appears to have been more protracted than CBA has let on, with hundreds of social media users telling the bank on Tuesday that PayID transactions they initiated last week had not been processed.The bank's social media team advised affected customers to contact the bank on Wednesday (today) if the "instant" transactions had not been completed, without explaining why payments executed last week were in limbo.The protracted delays have led to concerns among customers that the bank has lost their money.Here's a taste of what Pay-ID users were telling CBA on Twitter yesterday:"I cannot believe that I was told to wait until Wednesday, 3 business days - I am concerned that CommBank has lost our money.""Are you going to respond to the hundreds of comments on Facebook or Twitter regarding missing PayID payments?

Social media staff yesterday invited angry customers to submit applications for compensation after they were unable to pay bills using NetBank and CommBank Mobile App during the outage.Twitter users were yesterday demanding compensation from the bank to cover late fees they are likely to incur because they were unable to execute bill payments.As CBA left PayID users to ponder where there money had gone, one of the country's branchless banks ME Bank also confirmed that its internet service crashed on Tuesday morning. While an ME spokesperson said the outage lasted only an hour, customers told Banking Day that they were unable to access the site for at least two hours.
