I'm in the same boat now.
Flipped my Visa Platinum to HSBC Visa Cashback.
Flip request is successfully done.
I'll update if I'm charged JF or not.
Tag me if your status changes, in case you are charged in next statement.
Lucky you man!!
HSBC approving declined application 👌
I already hold Visa Platinum, tried getting Cashback, but for unknown reasons they declined !!
No source of information nowhere. I raised a complaint on April 27th, and no reply since then !!
