I had just bought something from Rick Hart, and I got a call from this number today. Did we all buy something from Rick Hart's?

Got a call today from this number on my mobile!  How did they get my number...I didn't answer it but as the above comments state its probably just crap!!

Get a call from this number and also 8664 3800 presume they are connected - no message.  No ability to phone, telling me all lines to the area are busy - try again later.

turns out it was telstra, calling about unusually high data activity on my phone.

Of course they have access to Optus' data.  Optus rent almost all their infrastructure and network access from Telstra.

I have just signed up with Optus - a brand new number which is only 3 days old and I am getting calls from this number also. Rules out Telstra unless they somehow have access to Optus's new mobile connections?
