I answered and they did not say anything. When I came back, there was a recording that said I had been contacted for market research, then it hung up on me.

This phone number (416 640 3489) belongs to Logit Group.
To stop them from calling you go after their phone carrier.
It is Allstream Corp. (formerly AT&T) in Toronto at 200 Wellington ST. W. Suite 1200 , M5V 3G2 Phone 1 416 345 4444. Call Allstream and advise them one of their customers is harassing you and if the harassment does not stop now you will lay charges of harassment against them (Allstream) for allowing their customer to harass you. Follow through by calling the Toronto Police or the RCMP and advise them of the harassment. The unwanted calls will stop.

This (416) 640-3489 number keeps calling me and hanging up. when i try calling the number back i get a message saying there voicemail is full. This number calls me 2 or 3 times a day. It's starting to make me worry.
