not able to return the call and the caller did not leave a message

THIS PHONE NUMBER SHOWED UP ON A CALL FROM VANCOUVER CANADA. FROM A WOMAN WHO CLAIMS TO HAVE FOUND A DOG AND WAS LOOKING FOR ITS OWNER.I AM A PET FINDING SERVICE, SO IT  NATURALLY SEEMED OK, BUT I WAS NOT WILLING TO GIVE HER THE OWNER INFO.  WE TAKE HER INFO AND RELATE IT THE PET OWNER. SHE HUNG UP, I COULD NOT GET BACK SAY COULD NOT BE DIALED ETC.. WE ARE STILL LOOKING FOR THE DOG.SINCE I SEE THIS BOGUS, I DON'T KNOW WHAT EVER PLAN WAS.I TRIED A REVERSE  SEARCH AND IT ONLY CAME UP TO A LAND LINE,AND I NEEDED TO PAY TO FIND OUT . THANKS I DIDN'T I FOUND THIS SITE ABOUT IT.

Just got a call from this number. Same thing as above, no voicemail and cannot call the number back.

I was online with Telus and their automated system said that I was calling from this number even though my cell phone is not even near this number.  When I checked online it appears that other people are having the same problem. If Telus picks up on the automation, then I am wondering how this phone number gets 'attached' somehow to our numbers?

the # called me, left no voicemail or message.
