I called back number (03) 9091 6028 reached IVR for a copany called Vodafone.

i got a call from this number and they ask for a pin?

I received 2 calls from this number. It's Vodafone want to market their new contract product... Told them not call back.

They called and it was Vodafone wanting to sell me something. I told them I was very gassy and they needed to speak up because I was on the toilet (I had bad chinese food the night before). They hung up.

They had my details and contract info... And offered me 1Gb upgrade? Don't know if it's legit?

It’s just vodafone trying to sell crap

I don’t know to whom was that phone number

Rang back with 1831 in front of number and got busy signal.

Not sure if this number was just a miss dial?
