I've spent a bit of time on the phone to Vodafone over the last couple of weeks. That included more time on hold than I'd really like, but I accept these things happen.
But they've made one important change that makes a significant amount of difference for me:
No Bic Runga on endless repeat!
Huzzah!
On a slightly more serious topic, the service I've had from the staff in the call centre has been excellent of late.
