Trial products question

So, I started promoting a $1 trial product like 1.5 weeks ago and so far I've had 5 sales. Well, 2 of those were apparently cancelled(transactions>next payment date), but for 3 of them, the next payment date seems to be changing :/... Like, the initial orders were over a week ago and two of the next payments were supposed to be on the 3rd and one of them was supposed to be on the 4th. Then, it was the 5th and 6th. And now, the next payment date for two of the orders is the 8th and for the other one it's the 10th. I'm just not getting this, since the trials for these 3 orders were supposed to be over by now and they should have been rebilled. Am I ever gonna get any money for these sales? Also, CBtrends for this particular product said that the $ per initial sale was $0(since it's a $1 trial), but that the average $ per sale was $35(since it's a subscription product, I guess). This is my first time promoting a trial product, so any help is appreciated. Thanks.

Are you sure there haven't been new orders?? Those dates shouldn't change at all....

Yes, I'm certain.

I know this is a semi-old post but I might know what's going on. Since subscription products automatically bill after the trial, it's possible what's happening is upon the first try, the charge doesn't go through, and the date changes because the company tries again the next day, and the next, etc., until the charge goes through. Eventually the company will give up and kill the subscription.
