He gave me several reasons why this could happen.
1) If you have a Credit card on the account, it takes time to mingle and send between the two companies, this can result in a on average two day lapse in time.
2) They credit accounts time here and there. It's usually a full 24 hours, which can add up after a while. If you have a continuous payment, and your account does not drop to "Frozen", this time is not consumed, until your account does, and then you get a few days at the end of the cycle to play this built up time. This is what I had, this is also the most common.
3) There are some times pure flukes in the system, which much like #1, takes it's time to mingle, and kick into effect. You have to consider their subscription base, and the amount of accounts paying, something along the lines is bound to mess up.
You prob have experienced #2.
