I have been called 3 times over past week by this number, it hangs up when I answer

Made a point of saying they were ringing from Australia and that they were doing an economical survey. That’s all I got before I hung up. (08) 7282 7013 rang last week.
Funny how the numbers are one apart. Phone named them as Contact 4 and Contact 5 respectively.

Keeps calling and hangs up when I answer. I have now blocked this number

Caller: Scam

Scam caller - ignore this number

Pestering calls this week from this number - ignore if you are contacted.

This number has called me many times over the past few weeks never says anything and hangs up after a few seconds

Seems to be an electrical business. Several times in the past week. No message left

I have been called twice this week from this number, must be a scam as they do not leave a message. Also I have been called twice in the same week from (08) 7282 7013 with no message once again. This string of numbers has been reported else where:-
(08) 7282 7010
(08) 7282 7011
(08) 7282 7012
08 7282 7013

Caller: John

John from Insight Australia doing marketing research. I asked him to repeat the name of his company. I asked him if his company was a data gathering company and he hung up on me!
