I had 3 calls from this number and 2 voice messages they didn't leave a message though. When I called and hour after missed call it said number was disconnected.
I have recently had a washing machine replaced by Samsung. I notice a person mentioned above it may have been a call from Samsung.

I think this was a Samsung feedback call following TV repair. She was only interested in ticking boxes, not in any discussion or helpful advice from me!

I called back number (03) 7267 8641 rang 4 times then goes to busy tone.

called today. No message left and cant call back as the "line has been disconnected"

Rings me, leaves no messge and when you ring back missed call, the number is always engaged. Every time!!!
