I just received my COB card and I have called them on three seperate occasions to find out the date of when they will report to the credit bereaus. I was given 3 seperat answers from credit one. The first was the last day of every month, the second was 3-4 days after my payment due date, which is the 15th of everymonth. The third answer was 30 days after my payment due date. So with three different answers I am affraid to use my card again, because I dont want to risk it being reported when my limit is high. I have made my first payment and left about a 20% balance on the card. My question is does anyone know when Credit One Bank reports to the credit bereaus. Thanks any help would be appreciated.
