Did you just re submit your entire application or just your OWP?It’s sad to hear that your application returned back due to insufficient fees.i had the same issue and i resubmitted again,its been 2months and a week since i resubmitted the application..i feel like resubmitted applications takes bit more time to get processed,I didn’t get AOR but inside the returned application they wrote my application number i noted that and after a month & half i was able to link my application.
In my case it was only my husbands OWP that was sent back
Thanks
