I am having trouble identifying what kind of appointment you are requesting. I do see that you last spoke with our Account Review department. If you would like to speak with this team, please give them a call as support does not schedule appointment times with this department. See their availability and phone number here.
If this is not the type of assistance you are referring to, please send us more information in an email to social_support(at)constantcontact(dot)com.
I am sorry to see you go, but I understand why. We do ask that you call and speak with our Billing department in order to cancel your account. It should only take a few minutes of your time and they will not pressure you to stay. Please click here for their hours and contact information.
