Are you going in and telling them you want an alignment or telling them you have a problem? Shaking steering wheel or a vibration usually is not a sign of an alignment.
Can you give a more detailed explanation of when the shaking occurs? Such as when applying brakes? A certain speed?
Something like a warped front rotor might shake a little but you should feel a pulsating in the brakes when used.
Did the issue start before or after the tires were put on? A new tire with a belt issue could cause vibration problems. Move the front tires to the back to see if the problem moves with the tires
An out of balance front tire could cause it all the time.
Worn steering components could cause it also.
Did someone hit a curb bending a wheel?
Someone really needs to jack the car up an give it a thorough inspection. With the wheels hanging in the air, checking for loose or worn components.
