Beware the scam involving your accepting a correctly named and addressed package you weren't expecting.
This can be a high value item, typically a mobile phone.
The next phase is an email explaining that this was all an error, and that a courier is coming to collect it.
He takes it away, perhaps even giving you a (worthless) signature.
Next month you receive a bill from a mobile phone company, confirming your account opening, and 36 £50/month payments (plus loads of recent overseas call charges).
You say you've never set up such an account, and don't even have the phone.
They'll probably agree to cancelling the account, recognising a case of identity theft.
But they'd want their phone back, pointing out (correctly) that you'd signed for it, or been photographed accepting it.
Then you say you gave it away to a stranger, simply because they'd asked for it.
"Tough" they might say, "just pay us the £1000 for goods you've received".
