go to "phone" where you make the calls, then press "..." on the lower right corner...then "blocked Calls".

I don't see a way to view a list of people I have blocked anywhere.

Solution:
On PC/Laptop > Download the skype desktop program > log in > contacts > advanced > manage blocked contacts...
The rest is easyOnly downside is that you need to use a PC
