They keep calling but can't help me!!

<p>They keep calling me, each day for either a FNB loan I don't have or a Abdallah Crédit Card I don't have. When I call back the agent refused to take ANY of my details but promised she will try to see if they can get them to stop calling me! HOW WILL YOU STOP CALLING IF YOU DON'T HAVE MY DETAILS???</p>
