I receive calls from this number every day. As per the usual practice with these type of callers, they never leave a message. I recognise the number so don't answer it, but they still keep calling!

Persistant.... pests

Receiving calls daily, I am just hanging up as it is a bogus number.

I missed a couple of calls from this number (03) 9999 0031) and when I did answer the third time they hung up, I phoned back, they introduced the company as Lifestyle Services (?), and the lady tried to confirm my identity. When I didn't respond, and asked her what kind of company it is, she hung up on me.

These morons consistently call me as well. I have blocked them.

This number has just started calling me this week. 2-3 times a day. Called it back (as our Mortgage co is in Vic) and they answer it "Hello!!!!" With a great amount of attitude. No business name or any reference to who they are. Adding to my DO NOT ANSWER also.

I've been receiving at least 4 calls per day from (03) 9999 0031. Somebody must have given them my details, as I never answer unsolicited calls/emails. They Just don't stop, so now they're blocked.

First call I answered, from life style surveys, I politely told them I'm not interested, only to call back 3 hours later that day and have called twice a day everyday for the past week.

I answered this number and the next day i checked my email and I had been signed up to a bunch of things I never signed up to! Be very careful, HACKING YOUR PHONE

Let this number ring out. Glad I did after reading all the comment! Blocked the number, will see if they call via another number now.

Over this mob calling me every hour last night/over night
I've blocked the number on my mobile
I have no idea how they got my number

Darn pest, whom ever this is. I just hang up, but it doesn't deter them. Maybe an email to the telecommunications ombudsman will shift them?

(03) 9999 0031 is some indian guy cant understand a word my number is silent so how are these idiots getting our numbers

Im sick of these rude people calling me. I answered and asked who they were and they hung up on me. Lady name Tracey. I called the number back and i asked her why she hung up and she had the bloody nerve to tell me to calm down and then hung up on me. I rang back another 2 times and she hung up both times so i called back and she answered and i asked to speak to her manager and he said they are calling from "lifestyle surveys", i told him what happened and told him off to not call me if they cant ve professional. Just disgusting. I will report them if they call again.

Whoever they are, they're a persistent mob. 3-4 calls a day for the last month. And as im using an older phone, the missed calls kill my battery fast.

I receive phone calls from 03 9999 031 every day. I don't answer them, hoping they will just go away! However, last night they called me at 2am!!! Seriously?
