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.

They called here a couple of times, on my unlisted phone number. I don't give this number to _anyone_ who isn't either family or a close friend. I have two other numbers (published & cell) that I use for all business purposes. I let it go to the answering machine since we don't know anyone in Manitoba. They didn't leave a message. If this is a market research company, then it's even more puzzling. I understand random/robot dialers may reach unlisted numbers, but researchers should have a carefully selected list. If they are truly doing research, the "do not call" list doesn't apply, but it does make it appear that AT&T is selling lists that include unlisted numbers.

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

almost all area code you listed are Canadian. On most plans you don't pay extra for north america calls.

I called the number back and it is for GM service the guy told me.
I said that was really strange since I own a Ford.

I say hello there is just silence.I hang up.Someone make them stop.
