I had the exact same message today. I definitely thought it was strange that somebody would give my number saying that I was receiving collection calls. This is absolutely against all privacy laws. I have been receiving calls by collection agencies for the last two years for someone who had the same phone number and obviously changed it...then the phone company issued it to me. It is frustrating to get these calls from bill collectors, but all I had to do was tell them that it was not me they were looking for, and they stopped calling. With some of them, I had to tell them two or three times, but they eventually got it. It just goes to show that there are deadbeats and scammers in the world, and we need to investigate things more closely than in the past, and, of course, have a lot more patience.
