keeps phoning buts leaves no message 7 days a week

I m receiving calls from this number at ll hours of the ay and night and when I don't answer, they hang up and call baack teo or three times. They are very persistent. Is there a wy to block the calls or is there somewhere where I can report this and have omething done about it?

Calls several times a day. Relentless...I’ll never pick up their call...what will it take to make them move on??

Calls everyday, yet never leaves a message on voicemail. Feels even shadier after reading what other have said about this Winnipeg, Manitoba number. Thanks.

I do't even answer my phone when this number comes up.I also let my answering machine get it.

Received 2 times yesterday, luckily i blocked that number !

Got a call last night.  Didn't know the #.  Said it was from Manitoba.  This was the first time.  And hopefully the last.

It's Ipsos Reid doing research

They call and I don't answer as I do not recognise the number!!

The person claimed to be representing The GM Master Card, and asked if I would take a 5 minute survey. I refused and hung up.
