Had a call from this number - took too long to answer the phone (I was busy). they hung up and didn't leave a message - obviously don't want to talk to me. Why can't these companies leave a message.

Just had another call from this number. Again, as soon as I answered, the call was ended.

Rang several times, did not bother to pick up.
Did not leave a message.

When you answer they hang up! Called about 4 times now.

many missed called from this # and when I have answered they hang up... if it is Westpac then I am really bugged by that

I have had about 10 calls from this number, they hang up if you answer, WTF.?
not wasting my credit calling them back.
