This is a collection agency.  No it is not a phone sex operator! LOL
As most collection agencies, they do call numbers that were assigned to debtors and in most cases these numbers have changed parties.  You need to understand that these are everyday people (like yourself) who are just doing their job.
If a number is called and is found to be the wrong number, it is immediately taken off of the file, but that is not to say that you will never get another call from them becaue files only stay on one desk for a certain amount of time and then are transferred to another desk, at which time the "NEW" collector will then call all of the previous numbers listed on file.
As for the people who make rude comments about this type of profession, it is most likely because they are the ones who are causing the non-debtors to recieve calls between the hours of 7am and 9pm Monday to Friday.  Now, that being said - if everyone paid their bills on time, then I would be out of a job.  So all of you non-payers I congratulate you for keeping me employed!
