XXXX XXXX, 2015 XXXX - Have received more than 8 calls on my cell phone from XXXX. I called the number and asked why they were calling. Individual immediately hung up the phone. Called back four times until finally the same individual decided to speak with me. He identified himself as working for an organization called NAM, and gave their website as website nam-llc.us.
