4 calls in a row from this number, annoying!

Oh and if you're avoiding picking up and still posting on here trying to figure out who's calling you, just pick up and see who it is.

If it's a wrong number, tell them. On the other hand, it could be a long-lost love, relative or friend. It's silly how afraid some of you are of picking up your phones. Sheesh.

I want to know that who is calling me from this no.

i got a missed call from this number last evening i dont know who calling

I am from states and got a call from this number this is weird

I was sleeping last night and when I woke up this morning I called a missed call from 1-(604) 638-0888. They had left me a message and played this really sounding music with no words! I had the missed call 12:50 am.
Could you please tell what this is or how to stop it?
Thank you and I appreciate it.
