i also joined this plan through strathfield, so im thinking its definately them and my plan in about to run out... how ever is it necessary to call several times every single working day!

Had the same number call me, it is strathfield car radio calling, do you have an Optus mobile and signed up through them? they are possibly calling to say its time to renew your plan and get a new phone if you like.

this number (02) 8741 3744 is strathfield group if they keep calling you call (02) 9598 8666 and ask for the manager in charge this number is there head office if not consumer affairs can stop them. f*cken s**t idiots

This number is calling me at least 4 times everyday.  I haven't answered yet as it is an unknown number - has anyone had a call from this number and answered?

yeah i get calls every now and then from this number too. I am with optus, but I didnt buy my phone through strathfield. if they are hassling you a lot you may be able to stop them by logging your number to the 'do not call register" https://www.donotcall.gov.au/ this is a government initiative to prevent telemarketing companies, etc from using your number...so i dont know if it will work for these guys esp if when we all join optus it is a clause in the fine print.

Yeah getting the call. Didnt answered but then left a Voicemail, Returned the call and they never called me back. And yes i signed up thru Straithfield but that was like 6 years ago and been thru 4 new contracts with optus already.
