Just got a call from this number as well, I'd say it's an auto dialler in a call centre.

Received several calls today and last week and after I answer, it hangs up.

was on behalf of Origin, I called them yesterday, to return a missed call, they offered a discount on my gas, I told them that I did not have gas.

They called again today, I told them that I advised them that I did not have gas yesterday, they will update their records

Some idiot has called me several times on this number - when it goes to Voicemail, there's no message, and when I pick up, there's no-one there.  Probably *is* some auto-dialer (like the one in the Simpsons)

It turned out to be a predictive dialer run by Dell. They rang today (and I did not hang up) and it was a follow up call to a purchase I made a couple of months back.

Would also like to know who this is.
