Don't answer - this was after I had filled in home loan form so maybe something to do with that company selling ph numbers?

same, they call wait around 9 seconds and hung up

Had the same experience, they hung up immediately after I answered.

Caller: Rate compassion

I spoke to them last year and rhey are calling to review but something is wrong with their phone line because they call, I answer, it drops.

I no longer answer calls from unknown or private numbers. If they leave a message, I reply.
This number left no reply.

I answered. The immediately hung up. Been getting a lot of spam mobile phone number calls that’s don’t leave messages
