They have rang me twice in the last 2 hours,who are they????

These people phone me every night - who are they?

numerous calls this week and everytime i answer they hang up

when i answer the call registers as "missed"

Caller keeps calling whenever I am unavailable, therefore I am unable to pick up my phone.

This number keeps calling and hanging up... Why?   What do they achieve?

I received heaps of calls from this number. the one time i answered they hung up straight away! What's going on?!

Maybe they outsource their call centre work to another company, but I had a "follow up" call from the insurance company youi.com.au after going through and getting a quote online.

Caller hangs up when I answer
