The top ten misguided corporate related contacts, lovingly collected by Loukas Christodolou.

10th
No, no, we're not Syngenta

9th
Caller: 'Diageo, hi.'
CW: '[muffled sigh] sorry wrong number'.
NB: Diageo are the beer and whisky-owning firm that hosted last year's G8 summit, which we profiled in great depth. But not to the depth of actually starting to bottle Guinness ourselves.

8th
Not a phone call as such, but we did receive a letter for the Marketing Manager at ASDA, offering the services of a public relations firm.

7th
This place is reserved for the many, many calls we get intended for Tesco, Asda, Morrisons and other supermarkets. Sometimes I see us as an overflow of these firms' customer relations departments.

6th
A call asking whether we were US military contractor Halliburton.
A few days later, a different caller, asking whether we were Kellogg Brown Root, a subsidiary of Halliburton.
I swear there's some group out there coordinating all this.

5th
Caller: 'Can I hire a camper van?'

Have we even ever written about companies that do camper hire? I'd start to suspect surrealist involvement in this one, except the caller didn't have a French accent.

4th
Just after our report on companies in Iraq came out, we got a call from 'HST', who wanted to be added to our comprehensive list of the firms that are currently basing themselves in Iraq. Wishing that all my research was this easy, I rang them up, only to find out that they wanted advice from us on how to get a few million dollars worth from Iraqi reconstruction work.

3rd
Caller: 'Can you direct me to a department where someone can give me a quote for an outside event that's coming up.'
CW: 'Sorry... outside event? We don't provide any such services, I think you must have a wrong number.'
Caller: 'Oh, so you're not Group4 Security then?'
CW: 'No.'

Joint 2nd
Caller: 'Hello, I'm from an Indian company that wants to supply security personnel to Iraq'. Oh really.
This is joined in second place by a Scottish gentleman enquiring what 'legit' security companies were working in Iraq. Erm, none.
How often do you get wannabe mercenaries phoning up your office, eh?

FIRST!
Caller: 'Can you direct me to someone who deals with overtime issues?'
Us: 'Err, what kind of issues?'
Caller: 'Well my daughter works at Wal-Mart and she's getting treated outrageously - I think it's illegal. You are linked to Wal-Mart, are you not?'
Us:'Maybe in a vague internet-kind of way... but we're not really big fans of them.'
The end result: The caller was sent a link to the rights at work pamphlet Stuff Your Boss Doesn't Want You to Know by Solidarity Federation, plus info on the main union contacts in their area.

Clear first place – wrong numbers used as a tool of social change.
