Cinder block wall collapsed 2 days after I built it - was it my footings or the block quality?

I stacked a 4 foot retaining wall in my backyard in Denver last Saturday, used rebar and everything, and Tuesday morning half of it just fell over. I'm debating if I should dig deeper footings next time or if those cheap $1.50 blocks are just junk. Has anyone else had a wall fail like this, and what fixed it?
