this person called and hung uo on me .. who is it

I was called three times in the last five days, answered twice, delay then disconnect "hang up".  My provider recommended "call trace" next time so RCMP gets info.  Then "call block".

7:16 PM Atlantic time - no message, several other times this month

said something about long distance... very poor english. I told the womman on the line that my number was unlisted and that I was concerned how they got it ... dead silence after that. I waited on the line until they hung up. I also tried to call back and got a busy signal. I've blocked this call; we'll see how sucessful that is. Now, I'm with eastlink phone and my parents are with Aliant - they never have this issue. Is there something wrong with eastlink???

They didn't leave a voice mail and it rings busy when I try to call back.
I use my phone for business and hate this type of call.
