Calling me 6 x per day how do I stop it?

Caller hung up when I answered. Reading other posts re this number, I guess they only want to leave a message so only 'unsuspecting' people call back.

I've just received a message on my answering machine from this number saying they are from the Tax Dept and I must ring them immediately. I don't bother to speak to them. 6 July at 11.00 am Toowoomba, QLD.

Calling for the "ATO" pure rubbish just hang up

I had the same, Matthew Clark and all, but from a slight variant to your number (02) 6188 5689.

I received a call didnt answer they left message claiming they were from the tax department ... Matthew Clark???
And not to ignore as there are charges against my name??? Definitely a scam..

Recorded message leaving this number with instructions to call in regards to legal action. More bullsh*t

This number range me at 2.20am this morning, the caller identified himself as "the fraud department of the Australian Taxation Office"
I impolitely told him to **** off. I would suggest to anyone who receives a call from this number to do the same.
