I checked it out and you got 5.5168398 DGC so far.
You will continue to get payouts from the pool even though you stopped mining for a bit...it's how PPLNS works. For example...if we were to find a block right now you would get 0.32673408. This will start to decrease unless you come back and maintain your PPLNS.
On the other pool you gave as an example you get 0.07965215/block (right now) but since they have 28 Mh/s you will get a payout more often since they will find blocks more often. It should about equal out over time. Maybe they had a lucky streak during the time you were there recently.
I'm sorry about your experience and your expected payout over the last day. The difficulty did increase and then come down during this time so that may have something to do with it.
Send me a PM and I will do what I can to make things right with you.
