Power Steering Fluid problems of the 2007 Mercedes Benz C230

Took car to dealership for recall service on driver airbag module, after driving away once job was finished noticed I was unable to turn steering wheel and the steering wanted to lock while driving. Srs light remained on. Smoke came out from under the hood and car was not overhearing, I called dealership and service advisor was gone and was not offered any additional help. I drove car slowly to my home and parked it on the street because I was unable to drive to the driveway. I opened hood and smoke was coming from power steering reservoir and also leaking fluid. I did not have any issues driving my vehicle prior to this recall service. I was put endanger along with my 2 kids and now having to fix other costly repairs and have no additional vehicle to drive.
