This number calls me very day at about 5pm. When I ring back they just hang up. Agree it is a phone company.

Told them 5 days ago, take me off the list and still calling..... NOT HAPPY...

Phone provider - sounded similar to Optus, but not Optus... Told them to take me off the call list.

Rang me today saying they are doing marketing at uni and wanted mags we have advertised in, we have had advertising scamers in the past and this is about the 10th call for the same thing. First one with a phone number though.

appears to be scammers wanting you to log into a website and saying your computer has a virus

This number rang me today and same thing - hung up! Looks to be Faktortel Pty Ltd from what I can see on google - a phone company (VOIP and broadband). If this is how they are trying to get customers they are going the wrong way about it!
