ABS lights on

Hi, i just had wheel bearings changed and now all my dash lights are on, the Brake, !, ABS, VSC. The garage who changed them said the wheel bearing they just put on already went bad without me even driving that and it kicked the lights on. I want to know what would have caused this or if that would actually even be the case. i just had them replace all bearings/struts/and the rear wheel drums too. plus tires. Any help would be appreciated!
