Thinking ....

Create an Account, there is an email notification.
Cancel an Account, there is an email notification.
That is great :)

1. What if?

What if the wrong account got canceled?
Can there be a 48 hour grace?

2. Alternate Idea.

• Make the Cancel feature Suspend the DID for 48 hours,
• then auto-delete if not re-enabled?

3. Lower Tech Idea.

Separate the list of Active, Canceled and Suspended
(Like you do with Transactions and Pending Transactions)

• In the Active List only allow Suspend and Restore.
  Put the Buttons at Extreme Left and Extreme Right.
• In the Suspended List allow Cancel and Restore
  Put the Buttons at Extreme Left and Extreme Right.
  
• The Canceled List becomes a 'so-sad-too-bad' List.
• VOIPo can charge a recovery fee for canceled account if retrievable.

My preference is Option 3.

Also on canceled accounts there needs to be a message like "Were sorry the number you have reached has been disconnected" or something. right now it goes to voicemail

1 And 2 is great. There should be a grace period JUST in case. However as a reseller you should suspend the service before canceling that way the client does have the notice. Canceled accounts still have it going to voicemail. Should it be doing this guys?
