who the hell is this person ive been getting these calls for the last 3 days and every time they just hang up straight away i think that once they said hi back to me when i said hello!

Had 2 x calls from these guys now, and i've missed both of them for various reasons.
On trying to return the call, you either get the busy tone, or 'the area you are calling is currently congested.'
Will probably take advice from -Dave - 17 Aug 2009- if i get another one.
Thanks mate

(07) 5562 9900 & (07) 5579 6400 have been calling my mobile 3-4 times a day.  When I did answer, I got a hangup.  I now do not answer these calls but they are becoming more frequent.  If you try dialling the numbers, it gives an engaged signal.   Who are they???????

(07) 5562 9900, has called my mobile once each day at the same time 1:43pm for the past 2 days , hopefully it stops here, but thanks to everyone online for your comments or i'd still be trying to figure out what's going on, now i can ignore all further calls. :)

You will find the hangups are because they have an auto dialler that only switches to an agent once the call is answered, hence they 3-5 second delay between answering and hearing someone. The reason someone often isn't there is the dialler has no idea if an agent is free when they dial, so when you answer if no one is available they hangup on you.

PS Just received a call from this mob (a hang up), not happy as I am in the UK for the next 2 months so no doubt they will be calling all hours of the night, UK time.

It is from a seminar company about homes because one called me from (07) 5562 9900 and i said i wasnt interested and now i get prank hang up calls from them cause they are bored useless idiots that have nothing better to doI
