I get missed calls from these two numbers at the same time everyday. But when I try to return the call it always says not in service.

(02) 9539 8807.
This number called me, I missed the call so rang them straight back.
A recorded message says the number is out of service!! Very strange.

I keep getting calls from (02) 8004 0029 and from (02) 9539 8807 to my mobile but when I ring back, the numbers aren't in service. I presume they are telemarketers ...how do they get your number?

Rings and hangs up
