THIS NUMBER I DONT KNOW BUT RINGS EVERYDAY DOES NOT LEAVE A MESSAGE. I HAVE GOOGLED THE NUMBER AND THIS IS WHAT CAME UP (02) 4783 8033 is a Fixed Line Telephone Number and could be a Spare Number.
However, number (02) 4783 8033 might be spoofed by scammers who will manipulate the number so that the call appears to be coming from a local or well-known phone number, making it more likely to be trusted or answered.

the call mentioned it was potential fraud no message was left

Caller: I don’t know

Claims to be a free hearing test service. Called after 8pm.

got a call from this number, no message left, spam on google about 16.00

Rings my mobile every day, but no msg.But my mobile says "Potential fraud"

Caller: I don’t know

Has called twice Wednesday 27th, once the next day and once the next. I don’t answer. I googled the number it said it was a fixed line but most likely be spoofed by scammers.

Three calls from them so far. I haven't picked up and they never leave a message but my phone lists them as suspected spam

Caller: A hearing service

Same as everyone else has said, however I've rung them back 3 times and told them to stop calling me, yes they still do! I'm not sure who to complain to about them but clearly they don't give a crap what anyone says to them.
Aust accents too so not a call centre in India somewhere where there could potentially be language barrier issues. Extremely frustrating!

Caller: Amplifon

Claimed to represent Amplifon, hearing care specialists offering free online hearing tests etc. At best, telemarketing, and at worst a scam; either way, a nuisance. Be cautious, and don't answer any of their probing questions with the word "yes" just in case. Or is my paranoia showing???

Keep ringing but no talking possibly scammers so annoying
