No, the cannot delete your account. I would contact the Sharp HR about your account. Are you still working for the company? If not, you could roll the 401(k) into an IRA account and have more control over it. However, you may have benefits to leaving the account where it is. This is something I would determine for a client after discussing the pros and cons of your individual situation. You can contact me directly for more specific information.
