Various social media users have also said that they have had their Ulster Bank credit and debit cards declined while making purchases.
It is believed that the "glitch" affects transactions that have been applied to customers' accounts since April 20.
There is no timescale yet for when the situation will be resolved.
A spokesperson for the bank urged customers not to resend payments, as they are working on getting them processed again as soon as possible.
