I want to start off with how I had recently discovered pay in 4, and decided to see what it was about. I had selected an item of my choosing about a week before the day I got paid, and kept checking to see the rates, I’d say about 4-5 times in total. I would just back out of it after it showed me how much it would cost each two weeks. Unfortunately, the day I got paid and went to purchase the item, I was saddened to see that when I went to apply I got the message that “Application information tied to unusual activity”. I have no clue what this could mean or why I was denied. Any idea what went wrong? What I can fix? How long until I can use it again?
