Caller: Telesales for wine merchants

I've contacted Telstra about my new phone & number. Only had it 2 weeks and I've had 9 calls from unknown numbers starting with 03 9121 and all have been telesales from wine producer-retailers. If I miss the call they never have the courtesy to leave a voice message. Telstra say they'll monitor my incoming calls. Perhaps thats why the previous owner of the number turned it in.

Had 1 missed call every day for the last 2 weeks, it's on block and still get a message with the missed call, comes up as suspected spam, hence the block. They never left a message before blocking them so don't trust them
