What to do if you accidentally sign up the wrong credit card?

Hi Anon,

I assume your card has already been approved?

If you applied for this card to get the signup reward, fulfil the minimum spending and hold the card at least until you've received the reward.

If you cancel the card and apply for the correct card now, you won't be eligible for the signup reward because you're no longer considered a new customer. So there's no point in cancelling it now.

After receiving the reward, you can apply for the card you originally wanted if you still want it, and choose to keep or cancel this current card.

Hope this helps!
