Unrequested Vodafone Call-Ya pack received

Well, I couldn't find it in the search, but this morning I received a Vodafone CallYa pack (SIM card and PIN).
Trouble is, I didn't order one.
Now I'm still on hold with them by phone (nice that they hang up on you by the way) and am also in touch with my bank.
No bank cards or ID is missing - I've checked.
Has anyone else had this happen?
I'm a long term contract O2 customer so it isn't as if I'd bought it by mistake...

EDIT: ah-ha!
It's a new direct marketing concept by Vodafone.
They are sending people who'd they'd like to sign-up randomly unrequested SIMs and PINs - you can sent it back free of charge to the address on the docket.
Unfortunately, it says nowhere on the pack that this is a marketing action, so it is very easy to think that this is ID theft.

Great for those of us who got this just before sitting an exam and really got worried that their ID had been nicked - cheers Vodafone, you bunch of wankers.

If you don't want it I'll take it and anyone else who got one I'll take yours too if your willing to part with it?

No - I'm going to send it back with a stinging letter and also I don't really want someone else having a contract in my name thanks.

So if you don't return it, does that mean that you're agreeing to some kind of contract with them? I can't imagine, legally, how that could work! They can't expect everyone to take the time for going to the post office to return the thing so they must be losing out on a lot of money. What a bizarre tactic.

If anyone has SIM cards they don't want or even old mobiles I'm happy to take them too.

o2 did this in the UK, basically just randomly send a load of PAYG SIM cards out. There was literature accompanying it stating it was free and if you didn't want it, just chuck it or give it to a friend.

thought it was quite a good marketing ploy, myself. But, Katrina's example is a bit shit if you have no idea what/why/who it came from.

Lee Kun-hee, is that you? Things must be tight in the world of Samsung!!

Haha, it's like Donkey from Shrek. "Pick me, pick me!"

There is nothing - absolutely nothing - in the pack to say that it is a marketing action. It is purely the post-registration pack that you receive when you buy a CallYa card (I did buy one in NZ, but that had an NZ address).
AGBs appear also to be unchanged:


See and that's the thing - if I were to chuck it out, someone just picking it out of my bin and using it would imply that I had entered a contract with them.
I, as in under my name.
Sorry to get all Daily Mail/Fox News/etc., but it is a fantastic method for dodgy folk (unlike my respectable self of course) to obtain clean access to telcos.

So if you get one of these, either send it back (pref. by registered mail) or destroy it completely.
Because although I love bike cops, a visit from the BKA might not be much fun.
