Company repeatedly calls for a person who used to have my phone number. I have told them over and over they have the wrong number and to stop calling. Today I told the person to let me speak to their manager and they told me [***] you sir. I called back and asked for the manager again and someone hung up the phone on me. I called again and explained what had happened and asked for the name of the company and they said american medical services. I asked for their address and they refused. Said they were located in houston.
