Did they change the brake discs too? Otherwise there is no reason to touch the wheel bearings. If they did change the discs, they had to adjust the wheel bearings, which is a precision job.
Wheel bearings go out slowly, first they start humming.
If the calipher is seized, the brake disc and calipher will get hot, if it is wheel bearing, the axle will get hot, although given time, the heat will transfer.
They might have used the wrong grease for the bearing.
The master cylinder might be faulty, it happens sometimes, even with new ones, they build up pressure, but the pressure isn't relieved and the brakes will seize.
If you remove the brake pads and the wheel still has a lot of resistance, than it is the wheel bearings.
