Can I sue my cellphone company because while an employee was performing a service on my cellphone, he stole and sent himself private photos of myself?

I have evidence he did it because he sent it to his email, using my email account. I Facebooked the email and it is his profile. This was while he was clocked in the company, while wearing a company shirt, performing his job and representing the company. What can I do? This is causing me major distress because he can ruin my career with any leaked photo.
