Re: 3 alternative options
1) Visit one of Samsung's high street stores. Get one of their sales staff to use their internal contacts.
That assumes they'll want to help. If it's anything like the 3 or other phone stores I've visited in the past, then they'll do their level best to avoid doing anything that doesn't involve selling you something.
2) Carphone Warehouse.
After the hack? Really? When they won't even tell people how far back the compromised data goes or accept that relying on stored email addresses to contact people isn't enough when they might have changed?
