i dont know who this person is but never pick it up. if it's a collection agency and helen wong is who they're looking for as specified by previous posters, then it's very odd and suspicious because obviously we are not Helen Wong. Makes you wonder if this is some kind of trick for identity theft.

received a call from this number once or twice a week, i never answered it though, left a message once all i hear is background noise

No one talked but i heard people in the background

Calls every day mornings, days , or evenings looking for Helen Wong. Will not give the name of the company calling and will not let me speak to a supervisor. Promise every day to remove me from theri calling list and then call again the next day.
Shows as 11-604-606-7888 on my cell phone.

Its not a collection agency although they do the same thing. Just got a call today. Looked it up and found that it belongs to Times Telecom in Richmond, BC. They're trying to sell long distance, I guess. If you Google their number that's what comes up. What a bunch of a$$h0l3s trying to waste my minutes. Honestly, if I need their services, I find them and call them.

I just had a missed call from this number and would like to know who and where is it.

They called me 3 times today.  I wish they would stop.  Next time they call, they'll be greeted by the sound of my fax machine.
