Yeah, I'm having a pain also. I got a text to go to bank to verify some details. So I do and they realised I've had a few accounts before so had to "merge" them all along with the application (and do a 100 point check while I'm there, which clearly I had done online). Anyhow no stress, the kind gentlemen said he'd sort me out.
So today I received a phone call from him saying that the "credit" department said that something was wrong with the way the merge was done (I'm guessing the guy in the bank's fault judging by his apologetic tone) and that I would have to re-apply again. He said that was a pain and he would do it for me and fill out the form providing I give him my pay slips again. Anyhow I was concerned that if he applied, I'd be slugged the full first year fee and possibly not get my 60k points. He wasn't clued up on that so I said I'd authorise him to do the application (what he was asking) if he could guarantee the same conditions as what I signed up for. So I have to send him the link so he can find out. This is getting painful.
