Hang up calls. Call answered only to have caller hang up

Caller: imile

I missed the call, no message left. When I called back it was an automated message with options saying it was iMile couriers.

said he was from a place I recently purchased from and confirmed my address, and he was correct, then advised my order will be here in 3 days ...

Said he is from ali express and he said my name & address correctly.

Caller: Do not know. But he claimed he is amazon.

The caller claims he is calling from Amazon to verify the address. Then he read out my address correctly.

Caller: I don't know

Rang my phone twice in two days. No msg left so I didn't return call

They said I've odered tools ... i think its a scam
