Had a call this am too. No message left. only let it ring about 4 times so went to missed calls.

I also called the number back. Couldn't make out the company. Sounds dodgy and probably is. Not really sure how to report them or if there is anything that can be done.

Tried to call them back but answer machine saying they will endeavour to call back, cannot understand name of company as the answering machine message is not clear when they state name, sounds dodgy!

This is one of several mobile number used by a dirty rotten collection agency i.e. CPA who are ruthless and will not leave a message. all mobile numbers begin with "0451 518..."
