No empathy for personal tragedy - Customer Service Agent Constant Contact Employee Review

Nothing out of the ordinary. Only one thing that blew if for me. My father became so ill I was called home. I did not leave his side as I was not sure when he was going to go. I advised my supervisor that I did not know when I would be back and that I should be taken off the schedule. So, she proceeds to hound me with texts anyhow about when I would be returning to work, when I don't respond, she then tells HR I am abandoning my job.
