A Philipino woman calls and insists I registered for a cruise, No matter how many times I tell them I've not registered for anything, her response is "well ma'am I'm just calling to talk to you about the cruise you registered for".  Asking for her boss or manager results in a "I cannot give you that information, Ma'am I just called to talk...".

At my last contact I warned them I will be coming after them if they don't leave me alone - so far they've not called back.
