I also have iritating experiences with this number and its various other numbers. I have blocked all their number variants, yet new variants keep storming in every day. It's a real annoyance...

Very polite male voice, wanting to sound like my friend. Three calls now, over several days. I just had a call, and said I wouldn't speak to him, then I hung up. I know he wants to sell me something, but haven't stayed on the line long enough to find out what. Very annoying.

this number and multiple variants keep calling. I keep blocking but a new variant calls. multiple calls received daily. sounds like a call centre but no-one speaks on the odd occasion when I have answered. I don't answer anymore.

Caller: (03) 7037 6373

If you call this number back it says "the mobile service you have called it switched off"
This number or a similar number calls every day at the same time. Each time I block it and they call again with a very slightly different number. Hoping they will give up!
