If you read snap's reply you'll see that a NEW connection was installed. So the guy had TWO DSL connections.

your new provider provisioned a new connection instead of transitioning the existing one.
Yours was a transfer, so you never had two active connections.
Lurch:
Case in point my recent move back to Telecom, Telecom transferred the account over and advised that they would inform Orcon.
