Rang my mobile. Didnt answer as I was at work. Called back no answer...I dont know how these people get your mobile number.

Have no idea how they got my mobile number!

I got a call from this number trying to sell me something.  Was a lady speaking, sounded like an Indian accent.  Give some 3-letter acronym as the name of the company..  She said 'we talked about this earlier'.  Couldn't really understand what they were trying to sell..  i _think_ it shares?

Yes I'm in Sydney, my friend just got two calls today from the next sequential number (07) 5667 7155.  Told him not to bother.

I missed the call so called them back, something called BTI? PGI? Sounded south east asian lady asking me for my name, wanted to email me a link to view for something related to trading? (My guess was they wanted my email), I declined and they then offered to sms me something.

Dodgy, don't give out any personal info !

They called me i didnt answer as i didnt know the number. Have tried to call back and it is engaged
