I just had 2 calls, 1 to my landline, 1 to my mobile.

Both displayed as from mobile numbers, both un-known to me so I answered the landline, nothing but silence, and the mobile stopped ring at the same time.

I have just checked the other number and it appears to be the same calling company.

Here are the numbers that called:
0422 272 094
0402 123 625

Calls, waits for you to answer and then hangs up.

I said hello, they hung up.

Claimed to do survey When advised my no. is on No Call Register, became very RUDE towards me. Block this no.

"Craig from The Premium Group"

They call and hang up.

They r ringing my landline daily!!

They call but just hang up

Report them to the ato they will deal with it

I got the same, they claimed to be the tax office and asked if I owned the house.
Then ended the call.

Say their from the Tax Office
