Got a call from (02) 3456 7892 today. I answered it and without introduction the possibly Indian man asked me "was my sky box working ok?". I told him I didn't have one and he hung up. How rude!

Been getting a few calls from this number over the last few days, as soon as you answer it goes dead

I have had 5 missed calls from this number today, i have an answering machine but no message left!  It is clearly not a "normal" phone number, ie not a regional code and I certainly aint ringing it back!  Anyone know who it is?

Answered phone at 18:10
Caller: "is that Mr ...(my name)?
My answer: "Who are you?"
Caller: "Are you was satisfied with the way your Sky box is working?"
Answer: " I don't have a Sky box"
Caller: " Sorry to have troubled you"
Line goes dead.
dialed 1471 ->  (02) 3456 7892

Any help?

This number called me yesterday. They told me my Sky box needs servicing, and asked if they could pay a visit that very night at my home!! This sounded particularly dodgy to me, considering I dont even have a Sky box! I told him this and he apologised and hung up! Very strange indeed.
