I also have not been paid a few times. one being the 2nd to last day of last period. It didn't even register in my mind that it may have glitched, because i never heard of it happening before and it hadnt been as obvious to me as it was at that point.. because i did so much, just like usual. and that day my rewards should have put me over my pay goal, and that morning, it was still the same amount as it was the day before. I was so irritated that all that work for so little that i couldn't even account if i got any for that previous day or not!
