Xtendmedia keep falling

Hy guys.I kept their ads for about 20 days on my website.First 2-3 days they paid me about 3$ for 12.000 uv per day, then after few days they paid me 1$ sometimes less for 14.000 uv per day .At this moment reports look like this:
Impressions – 1,274,638
Clicks – 21,077
Conversions – 135
Click Rate – 1.65%
Conversion Rate – 0.64
Net pub comp – 66.74$
Net eCPM – 0.05
ROI – 93.73
WTF??Only 66.74$ for 1,274,638 impressions and 21,077 ?Thats poor.I took their ads off , and now im looking tho other CPC or CPM company…The sizes i used are one 468×60 banner and one 300×250 banner.Does anyone earn more than that with them?
