sittercity.com Deleted my account and then did not tell me why it was delted telling me it was company policy not to give a valid reason. Chicago Illinois

I joined sitter city two years ago in hopes of finding a job since I lost mine. I am a college educated woman, and I was hopefull about the site. I hadn't signed on in a few months because I felt as if it wasn't working for me, but I was still looking for employment. They then deleted my account and when I emailed and asked why they simply stated I violated TOS. Which I find strange since I haven't logged on to that site in six months. And that wasn't in the TOS. So when I called the place the woman was rude and curt and told me that the company could delete accounts just because they want to. And also that it's their policy not to tell you what TOS you broke.  I found that rude, and unethical. If something is going on I have a right to know and to clear my name.
