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.

This number has been calling me constantly and is very annoying as well.

I am wondering what would happen if we picked up the phone and do not speak;
leave the phone off hook for 5-10 minutes.

Has anyone tried this?

It's Ipsos Reid doing research

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.

Received a call from this number for a five-minute survey. It was for the bank I use . . . but I refused to give them any information like my e-mail address etc.

Why are they calling?

I received 2 calls from (204) 975-3301.  Luckily, I wasn't near the phone when it rang so I never answered the call.
However, I have received calls from this number in the past and if I find out who the caller is I will have him/her charged with harassment.
