This is certainly Amex, but it is also the debt collection centre for David Jones store cards.

Keeps calling and every time I pick up they hang up - super annoying.

it's American Express. It's there late payment/missed payment centre

I called Amex after reading these posts. The number is NOT an American Express number, nor is the 1 800 number they ask you to call back on.

It is American Express or David Jones Store Card, chasing up payment. Rings several times a day, doesn't leave a message and it is more than five days until my bill is due! Very tempted to add their number to my blocked caller list.

why don't they leave a message? and I don't have an amex card

dont know

This is a legitimate American Express number however most of the commenters here have likely received calls from a scammer spoofing this legitimate AMEX phone number. Do not disclosure any personal information unless already expecting a call from American Express!

Caller: “AMEX”

Phone rings multiple times per day. I pick, say hello and nothing until they hang up. When I let it ring, it rings out and never a message left.
A scam caller targeting something. I have blocked it, as I don’t believe this to be a way the real American Express service would be run.

Caller: American Express

Appears to genuinely be American Express chasing a missed payment.
However, they will call constantly (multiple times every hour) without leaving a message if they are unable to get an answer.
This constant calling goes well beyond what is reasonable for a debt collector to attempt contact and is well over the red line of harassment.

Caller: claimed to be American Express

It is not American Express BLOCK

They ring me, as they were chasing another person

Idiots. Why don't they get found out? Should be a law against it.

Idiots trying to call my 4G dongle. Just be aware that there is nothing stopping the scammers from leaving a comment here that it is 'legit' AMEX number - they swear! - NO credit provider would do this, they are scammers. Reverse name is DAVID JONES AME (from revealname.com),DOES NOT mean legit, just name registered to number!

first they call you from anonymous, & if you don't answer then they call you from this number

AMEX debt collector .

keep calling no message left. silence when answered

Hangs-up when answered. Never leaves a message

Caller called and it went to voicemail it is a 3 min voicemail of someone walking and you can hear background noise but no talking
