UnderDog Media Paying Nothing For 32,000+ Impressions?

Is anyone else on here using UnderDog Media?
I have been using them for a couple of years and although I was not making a lot (about $0.20 a month) I noticed that I was earning less and less over the past year. In the past year I have earned $0.01-$0.02 each month from generating around 2,000-7,000 impressions but last month really took the biscuit! I generated 32763 impressions and they paid me a grand total of $0.00!
They claim to be an CPM company and I did check to make sure the traffic was coming from countries they pay for.
Am I alone here?
