Hung up

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.
