Shocking Customer Service from CMH Mazda Menlyn

They promised to call me back yesterday amd did not. Today I asked to speak to the Foreman and he does not call back either. I am told my vehicle may possibly be ready tommorrow. In my opinion, the word "possibly" actually means it won't be ready tomorrow. I ask to speak to the Service Manager - no luck either. In today's society where there is so much unemployment, one would at least expect those who have customer facing jobs, to at least be good at them, else give someone the job who can offer good customer service. They have had my vehicle for over a month now.
