Disgusted

I was retrenched in April 2021 and as one of the top employees i couldn't believe that management couldn't even express their concern of me departing or even just to greet me on my last day. But what hit me the most was that I know have medical aid bills because they refuse to assist with the payments as it was not my choice to leave my job. And the medical aid company has put me on ITC. How should I find a job with a bad credit record.
