XXXX/XXXX/2015 I received a unknown call on my cell phone with a message left with a threat of a law suit from a law department ; the person calling did not leave there name or what law department they were calling from just the I needed to call Portfolio Recovery. The message stated I must call today to discuss or a lawsuit would be filed and delivered to my home or work between XXXX and XXXX on XXXX/XXXX/2015. I have not spoken to anyone as I received some strong messages from individuals in XXXX, XXXX, and XXXX leaving messages that warrant would be issued ... the message did not say by whom or for what ... just that I needed to call. The numbers were unknown and the tones of the individual leaving the messages were very strong and threatening like a scammer to take you information and steal your identity. I am very nerves as and scared to go to outside to my car or work.
