It"s a payment scam from the late 90"s or early 2000"s that got Providian, MBNA, and I think 2 other banks the largest fines ever at the time. I had a Providian card at the time and they would delay entering payments by up to 2 weeks in order to get late fees. I figured it out and called them. I went up the chain of command until I got one that admitted they were under investigation for their practices. I had a small balance, and they refunded all the late fees, paid off my balance, and closed my account. What tripped them up was the late fees were supposed to rotate to a different set of customers each month so most customers would just assume they were late and not worry about it. I got hit 5 or 6 months in a row and started fighting from the start. Here"s a link to the Providian case.
