Glad to see I'm not the only one who's been caught out by this.
I will be taking it further as the total lack of support from DJ has really annoyed me with this.
Allianz are now on three ignored emails and are refusing to discuss the issue over the phone so it will have to be escalated to the ombudsman.
DJ are even worse. I've had nothing but pre-written and unhelpful responses from them, the last stating "as your enquiry relates to our website, it's been forwarded to the Virgin Australia website team who will respond within 10 days". Had someone bothered to use their brain and actually read my concerns, the issue would be quickly rectified!
While Virgin may have a good social media team (and in fairness, Qantas seem to as well), their standard resolution procedures appear to be totally useless (again, not to dissimilar to Qantas). This issue, along with another serious complaint that was ignored by DJ about 6 months ago, really have changed by otherwise favourable view of this changing airline. It's a shame, they've got so much good going for them, but seem to struggle a bit behind closed doors.
