A customer took to Twitter to express her anger after being told her surname ’Ní Cathail’ wasn’t valid.
Three Ireland suggested online that she translate her name to the English ’Cahill’, which drew the ire of many users.
"Hey Caoimhe, have you tried entering your name in English? Is the translation Caoimhe Cahill?"
The company have apologised for the slip and say they’ll see if the issue can be rectified.
