This is a collector from NCA (National Credit Adjusters) They are now using cell phones instead of landlines. My boss has asked them several times not to call the office again but they continue to call using different numbers so the name doesn't appear on the caller ID. We contacted the Consumer Justice Group and we will file a law suit for harrassment if they continue to call after sending a "Do not call letter. We have several recorded conversations of them being asked not to call the business lines again but they continue to do it. You do have rights so please exercise them.
