It been close to 3 months since I'm using my Capital One Platinum, which was approved with $2000 limit. For past 3 months, I have been using the card for all my spending and paying off all balance in full after the statement date.
Today, I received an automatic limit increase from $2000 to $4500
I was really surprised to see automatic increase because after the first month, I applied for a credit limit increase in the app and it was rejected with reason "account too new."
