Engine Cooling problem

I attempted to have my radiator flushed and nothing would come out of the drain plug. What can i do to fix this?

What you could do is,put a cooling system pressure tester on the radiator,open the drain,then pressurize the system,the pressure should clear the drain,after it clears the drain,pour a pot of boiling water into the radiator slowly that should melt away the clog.
