This was a call center because I could hear many people speaking in the background.  The lady asked to speak with the person who handles the merchant accounts.  I told her we were not interested and asked her to remove our number.  She said she needed to speak with the person in charge and I explained she didn't, simply remove our number.  She said if that person was not available she would call back later.  I told her she was not allowed to call back because I asked her to remove our number.  I asked her if she understood and she told me to have a nice day.  Unbelievable.
