The "are your carpets dirty" people....  I received two messages at the same time/date from this company - one from 870-639-3973 and the other from 870-639-3143.  Then another call 5 days later from 870-639-3179.  Call back number is 469-277-7276.  Have received calls from them before so I have now left 2 messages on their call back number asking them to remove my number as I am on the Do Not Call List.
