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 answered and they were from Home Testing Institute doing a survey (no solicitation).  I know my wife fills out their surveys all the time.  They said that she can call back at 1-+1 877-990-3599 to get her number off of their list.  I'll let her decide.

Why are they calling?

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

Had a couple of calls recently from Manitoba (204) 975-3301. Am fed-up with tele-marketers - have changed my number to an unpublished one, and also there is a block caller service that my phone company offer. By dialling 78 after the call, that caller is blocked from your phone.
"Do not call" service is useless. Have reported numbers - nothing done about them.

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.

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?
