Duplicated messages and Premier Chat runaround

I've received 5 of the same message for a debit order on 30 October, the InContact Messages for 'New debit order(s) on Acc' has been coming up on my app since 9AM today (04/11). When escalated on the secure chat, I was told that it COULD be a system error the advice given was that I should restart my device. Restarting my device did not resolve anything and I was ultimately passed onto different people with no answers or resolution in sight. I'm still receiving these messages while I wait for my complaint to be attended. There was no update to the app at the time this issue; so must I resolve this by changing banks? I am now seriously considering this after the last runaround I received on the secure chat for setting up contactless payments on a new debit card
