I don't get the blocks I mine in Amplified mode?

I've gone into Amplified survival, and I tried to mine some blocks. I wasn't getting anything, so I thought it was just block lag. But I waited 5-10 mins every time, still nothing happened. Now it's been like 15 minutes and still no blocks appear.
I'm 100% sure Im in the right gamemode, too. Am I doing something wrong?

As caucow said, first make sure that you do /gamerule doTileDrops true
. After you do that, and it still doesn't work, make sure that you are using the correct tool to break the block :P. If that doesn't work, try and re-install Minecraft (I know it seems kinda lame, but hey, it works (sometimes)). If it still doesn't work, ask these people.
