Ive also received the call from this number this morning..i thought it would be some telemarketing or whatever...geesh i cant believe when i googled this number...so many unpleasant comments about it...yeah and when i called back my call was rejected

I live near sydney and got a call from this number too. I was in the shower at the time and when i looked at my phone it said i had two missed calls from them, 2 min apart.
i thought that perhaps "03" was an inter-state number, so glad i googled it and found this forum.
Its gotta be something dodgy!

same here. i got 4 missed calls from this number.
no one is there on the other line when i answer.
bloddy annoying.

Same deal as everyone above I think. I've received calls over the last three days from the (03) 9838 2018 number as well as (02) 8114 3800.

I've answered once and it was a man with an Indian accent (always suss from an unknown number) offering me a better deal on my Optus prepaid. I didn't hear all the details cause I was chasing my dog who got out while I was trying to figure out what he was offering, but it was something like $19 a month and $50 worth of extras. Which is stupid cause I get more value from a $30 recharge anyway. He said I'd been selected by Optus for a new prepaid plan. Whatever...I just hope they stop calling.

I have received a call from this number as well, I would never be tempted to call the number back, I'm sure it's no different than any other bogus calls,who in nearly all cases charge you when you ring them back , make sure you check your statements.

I had the same call just a few mins ago. from (03) 9838 2018. It was Oceana Customer Interactive Services.  I went to the do not call website and logged a complaint.
