No voice speaking. I didn't answer the ongoing calls over last few days. Received a voice mail message with a female repeating hello.. I am going to try blocking the number

Just keep calling me for several times, and didn't say anything after I picked up

Caller: Vodafone Sales

Vodafone trying to up sell my plan that is only a few months old. I have opted out of their marketing calls and texts but since it is a call centre they don’t seem to give a rats ass. Calling me every day, this on top of all the election calls from the Liberals I don’t think I should bother answering the phone and just start blocking all the numbers for Vodafone.

Vodafone

high pitched tone upon answering call

Called me twice but no messages.
I looked it up too at Vodaphone, one of theirs:

RE:Phone numbers we use to call our customers.

Caller: Unknown

Got 3 missed calls in the last 2 days. Answered and they said it's Vodafone and wanted my 4 digit pin to offer me new deals that I was picked for! I politely said No Thanks and hung up. The number seems legit but "~Disp4" is what comes up with number. Would it not say Voda? It's a worry

Caller: ‭(02) 9015 3806‬

I answered the phone, long pause before the call worked and the guy replied back. He said Vodafone but it was so scripted that I didn’t feel it was safe. I only changed my plan a few months ago.

Rang my mobile, did not answer as I don't answer numbers I don't know. They sent a voicemail with nothing on it. Checked number and have blocked it after reading comments.

If from Vodafone , but why they call on Saturday ? Is it legal ?

By no means am i saying don't be careful, but some of the comments below are a little OTT.
Checked with Vodafone, real easy as they have online chat. The number is listed on their site. Its likely from their outbound team. ie your contract etc may be up soon .

Got five calls from this number yesterday …. not once did they respond, always a silent line or they just hung up

no sound on other line

Received a call fr this number, didn’t answer, but think suspicious.

Got call from this number. After a while there was a beep and a man answered hello... but them the call is off. Very fishy and i had a feeling it is not legit. That is why i googled it and found this thread. I would register this caller as SPAM. Not a normal business would do this dodgy call.

The caller hung up when I answered.

Caller: Claimed to be Vodafone

Called asking for Vodafone account pin - either dodgy or bad business practices

Caller: (02) 9015 3806

THIS IS A SCAM NUMBER!!!!!! They are trying to get your personal account pin numbers to access your account. The links on their txt messages are even fraudulent,
if these guys ever ring you dont give them ANY INFO on your account. HANG UP!!!

Caller: vodafone

still trying to cold call, but i only upgraded last month in store. I doubt they have access to my account then. Dodgy Voda Spam
