Update: Not surprisingly, I registered the issue with the double credit check with HSBC 2 days ago. Was told to expect a call back yesterday - nothing. Seriously not expecting good things from this.
Next step - I'm going to find the Equifax and Experian request forms to complete this weekend and send off to get it scrubbed as based on all actions taken by HSBC so far, I've zero confidence in them correcting it.
As a data point on their 'effectiveness' shall we say....
Day 0 - Single Application Lodged online
Day 1 - Credit Check registered on Equifax
Day 2 - Nothing
Day 3 - Checking the application, it said HSBC not able to offer me a credit card at the moment.
Day 4 - Missed call from them, advised that my application got duplicated - one has been stopped, and the other is proceeding and I need to send in payslips. Cant submit electronically as the new reference number doesnt work online - have to email. Confirmed with agent that no 2nd credit check would be done.
Days 5-12 - various calls to check progress 'no update, but they are verifying and will have answer for you in 3-5 days'
Day 13 - Called to find out card approved.
Day 19 - Card arrived
Day 20 - PIN arrived
Better yet, I once a long time ago had a HSBC credit card that I cancelled - but it shows up in my internet banking profile? Cant access any information about it and am certain I closed it down (seriously, 5-6years ago it was and did have an annual fee - so with it showing a zero balance, I'm sure its just old profile data), so hoping its ghost presence doesnt cause me problems with the 60k QFF points. I think I'm relatively OK as I've already (can you believe it) got my first statement - and its got the promotional rate for the balance transfer on it (BT ends up in offset - $199 turns into $50 annual fee taking into account interest saved)... so I'm hopeful.
I will be kicking and screaming if they arent awarded - the sole purpose of obtaining the card is to get 60k points for a net card fee of $50 (Balance Transfer worth $150 to me).
