Countdown customers were woken up in the middle of Saturday night by a text message promoting a fuel discount.
The text message read: “Save 40c/l on fuel with $200 spent in-store at Countdown this Sat 28 - Mon 30 Jan 2017. T & C in-store or ph 0800404040. To cancel Onecard alert, reply STOP.”
Countdown has apologised to customers and said they were investigating the issue.
