Phone # 414-431-4450 This company is a piece of work!!! They called my unlisted cell phone number and asked for my mother. I asked them who was calling and they wouldn't identify themselves. I told them that this is her adult daughter, we do not live together, and asked why they would be calling me. They said that "by law" they could not say. BS! I asked how he got my number, and he couldn't say. He couldn't tell me anything except that his name was Justin and to call my mom at work and give her the message. I did and she called them. It turns out she owes a very small amount on a medical bill. I called the company back, the woman that answered just said "hello" like it was her home phone, I asked for Justin and she said there was no Justin there. I firmly explained that I just spoke to Justin five minutes ago and I need to speak with him again! She wouldn't allow me to do so, I explained that they had no right to call my unlisted cell phone number, even if my mom may have listed me as an emergency contact, that information was not legally obtained. She could say nothing about it. I demanded to speak to the manager and she said she was the manager, why would the manager be answering the main line? I told her I need to know the name of the company and she said OAC, I asked what OAC stood, like an acronym, and she said "nothing!" I informed her that the information she obtained was not legal and that they must delete my number and I will be filing a formal compliant!
