I got a job with a woman and after * days of my job I was called for a family emergency and had to leave asap .As soon as I found out I had to leave this position do to this family emergency i automatically sent her a text of this happening and I was very apologetic to why I couldn't work for her family any longer .After * day I see that this woman tryed massaging me saying I should be ashamed of myself and she hopes I wouldn't do this to anyone else family so I in return wrote her back telling her she should be ashamed of herself writing to me when I am in a family emergency.. I have over ** years with a * star in references and don't want this woman writing a bad review so how can I block her from my page and make sure she doesn't give me a bad review.
