Continue to call every day and leave messages - same script of "very important that we talk to you today" and "please respond so we don't have to keep doing this." Got tired of the messaged so I finally answered and said I don't know that person and he was harassing me, asking more questions, using my spouse's name. Do not give them any information. He said he would continue to call me every day and I said I would get a lawyer if he didn't stop. These people are evil.
Just received a call at work from these people....I called back, was put on hold forever. I hung up, since I had better things to do. 3 seconds later the phone rings and the person on the other end was very rude to my receptionist.
