What's the point of selling a motor-servo shield that can't power a servo?
Basically you don't need a motor shield to power a servo. It is powered direct from a supply and the control signal is a simple logic signal from the Arduino. A servo is like a motor, built in motor shield and built in positional feedback mechanism, all it needs is a logic control signal in the form of a pulse.

Part of the problem (at least for beginners like me), is that for every case of people asking about servos crashing their Arduinos, there are 10 projects online with diagrams showing a servo directly hooked up to their board.
And there is a fellow in Nigeria who needs you to help him ship some money out of the country for which you will be handsomely rewarded.
