A number of FNB Connect subscribers were hit by a billing glitch at the start of June, which has since been fixed, said the bank.
One FNB Connect client on a Top Up contract told MyBroadband their account was not credited with new airtime at the start of the month.
They were also unable to make calls, despite still having airtime which rolled over from the previous month.
FNB Connect told MyBroadband there was a billing glitch on its system which affected several customers.
“The situation has been remedied and services have been restored,” said FNB.
