Received a call from (03) 4344 4653. Bakery Hill, Vic. Blocked the number on my iPhone and the same number called 5 minutes later after being blocked. How does that happen?

Called me yesterday at 1:44PM, today at 1:48PM. Left no voicemail. Will block

Have had 3 attempted calls from this, even with said number blicked

Called back - rung for a while and then got a 'goodbye'

Caller: Keeps calling

Nuisance

They called my mobile. I called back from a landline, and it rang with a really odd dial tone a couple of times, then glitched like it was being transferred, rang a few more times, and then suddenly an automated voice said, "Goodbye," and the call cut out.

So I'm thinking.......... scam.

Answered it, but no voice, complete silence then they hung up.
Very annoying.

Caller: Offer Insurance

call me like 10 times a day- requested the ABN for their company to lay a complaint for harassment and the Indian bloke had no idea what I was talking about- i pressed for more information and he placed me on hold the call was then dropped, I called the extension back and no answer. trying to sell electricity plans.

Bakery Hill, Victoria. Several calls from different variations of this no.
I keep blocking the no’s. but they persist by using a slightly different no.

I tried to call back this number and said the number was not in service

Oxygen Thief
Selling energy plans, how many times do you have to say no.

I called back the number (03) 4344 4653 and the person I spoke with said the company is Offer Assurance
