If they ring and don't leave a voicemail, they're not to be trusted. They called me twice in the space of 1 minute, didn't leave a VM either time.

Called to tell me that they were deleting my SIM. When I told them they had called the number of the Trading Standards Office, they hung up immediately. Says it all really.
