Vanquis balance transfer card - not being able to balance transfer at application stage

l.c.elliott

I have a balance i need to transfer from another credit card. I applied for a balance transfer with HSBC but without going into details, its taking FOREVER and I dont even know if I'll be accepted, so I went back onto an eligibility calculator and saw i was pre approved with vanquis. I applied and the next day I got a message saying I was approved and they were sending my card in the post. At no point in the application or approval process have they asked for details of the balance I want to transfer. I'm assuming I'll be able to request the transfer once my card has arrived? In the past when ive done balance transfers with other lenders, ive been able to do it as part of the application.

Has anyone experienced this issue of not being able to balance transfer during application stage? Have you had to wait til your card arrived? I've got a balance accruing interest so I'm keen to get it moved ASAP.
