I received this call on my mobile, & a woman told me where she was calling from (I didn't catch it) & that she was not a salesperson trying to sell me anything. She said that she wanted to inform me of government benefits for people under 59 years of age who still have a least 5 years remaining in the workforce. She was quite polite & called me 'sir', but I immediately became suspicious of why she had my mobile number, so just replied that her criteria did not refer to me & hung up.

I called back number (02) 9651 7495 rang once then goes to busy tone.
