i keep getting calls and they no my name HELP

I picked up and they hung up straight away. :S thanks to this, gonna block this number now.

Missed call searched this number on the internet and found out its a telemarketer

Same issue. They keep calling.

Lifestyle - life insurance company has called me three times in the last week on this number

Same issue with this number. Calling every day but no answer. When calling back says stay on the line!

I called back number (03) 8820 3975 just kept on ringing no one answered the call and never got any voice mail.

Keep getting calls from this # when calling back Indian accent says "PLEASE STAY ON THE LINE YOUR CALL IS VERY IMPORTANT TO US" then you wait forever and nobody gets to you. Have had this call many times before but a different # so they must use different #'s all the time. Just tired of blocking #'s from the same caller.
