When you emailed email@example.com did you use the same email address you used to register ccleaner? That should have put you in the priority queue, I assume you've checked your spam folder for their response.
Are you using easyclean/health check or custom clean? If the latter did you move your banks cookies to the cookies to keep option? What exactly do you mean "not able to access"? What happens? (I.e. Website doesn't load, doesn't accept my login credentials etc).
I've flagged the staff to look for your support requests.
