Fired for being scammed by fake IT person - Operations Manager Target Employee Review

Company doesn't stand behind you if you make a mistake. I was scammed by a fake IT help desk person. I was told it would be fine, because it was not my fault. Then two days later I was told I was being fired, because the legal team in Target Headquarters decided to let me go. I had never had any type of discipline or mistake in my time with Target. I was also told that this scam happened to many other people in the company, who are also fired for it.
