Same story muliple calls & no answer

I got 6 calls in 10 minutes from this number. I didn't answer, they didn't leave a message.

I'm wondering who's that?

i receive phone call from that number and they leave music on my answer machine . if i answer they don,t talk.
this  kind of marketing is very agressive on my nerve . please stop those stupide people hat are not polite at all

Got called twice today.  When I answer, it hangs up and when we don't answer, no messages.  If we call back, no one answers or we get a busy signal.

I got this call : no one talks when I pickjust after I got a call from (514) 667-5044also on these lists of weirds calls
