Norton Family Premium does not work

I am facing the same problems, Well while using the free version all was good but after purchasing the Premium we are having problems.

1. Unable to Log In to website as it gives the message Signing into your account & the yellow circle keeps on circling.

2. Unable to Add my sons Mobile Device Samsung S4 as I get the message Failed to associate this device to childs account

3. On my PC my son's user login works fine but when my daughter tries loging in it does not & gets locked out saying she is out of time

I have tried all the steps to resolve, unstalling & reinstalling. I am feeling cheated as after paying we arent getting the desired services. Could you please have this rectified or process my refund.
