After reading all the horror stories around here, it's good to have some different experience to report... Yesterday at about 6pm I contacted the Paradise help desk through e-mail, asking to move an e-mail mailbox from someone else's account (MIL, mother-in-law) to my account, because she had closed her own Paradise account when moving to broadband with another provider (unfortunately they don't live in a TCL area).
The reply e-mail, asking for a phone call from my MIL to confirm the request came in the morning, even though it was a holiday. After confirmation the move was completed in less than 24 hours total. All done via e-mail and no wrong configuration or anything terrible.
I know it's Paradise.net, and albeit they are technically TelstraClear, I am not sure they share the help desk. But it is still the same company, and a very good service.
