Carribean Cruise Lines Harrassment calls palm beach, Florida

I have been receiving numerous calls from "Caribbean Cruise Lines" 1-800-446-1524. I have asked EVERY time to be removed from their list yet they keep calling. The last call was ridiculous. The guy got mad when I told him to remove my name from their list and I explained to him that for weeks I have been receiving calls from them and every time I ask them to not call me. He said "i'll put you in the do not call list but you will be receiving calls for the next 72 hours". I told him that they need not call because this is turning into harassment. He said it's not harassment and that they were going to call for the next 72 hours. I asked for his name and he said "what you don't remember? you forgot already, wow what is wrong with you that you can't remember" I asked him several times for his name and every time he mocked me and talked to me like I was stupid. Finally he said Joe Smith was his name and laughed. Honestly, I do have some brain damage due to a brain tumor and the brain surgery I had to remove it in 2003. I do not appreciate that this company has called me numerous times and have upset me so many times. This telemarketing office should be shut down,  I have serious medical problems and stress is something I don't need
