Hey everyone this is a furnace cleaning companhy. I bet they dial our numbers and not say anything because at least they can write our number down as proof they called and get paid for doing nothing. Ha

Just got a call from them this afternoon around 1:50pm.  Left no message.  I called back and it rang about four times, then sounded like it connected but then no answer.  Suspect duct cleaning telemarketer as my wife picked up a call from some company like that last night but i was not available so they said they would call back that evening.  Never did.  This may be them trying.  Incoming calls close together from (403) 266-1107 and (403) 266-1131.  I called both of them back - same thing.  So telemarketer of some sort.

Got a call from this number and noone answered me when I said hello repeatedly.  I could hear people talking in the background like it's a call centre of some kind.

I also got a call from this number. Didn't make it to the phone, called back, rang for a minute and a half, then it sounded like someone picked up and hung up right away. No voicemail or anything.
