Hi Jodie👋 This looks like our branch staff’s customer care number, they’d use then when proactively contacting customers regarding our financial health check service. If you’d like me to get in touch with your branch to double check this and rearrange the call let me know-Olivia https://t.co/5uVyDVpsKw
