Continuous Harassment

This company continues to call me from different numbers asking for a person that is obviously not me. I have given them my full name several times yet they continue to call me. During my latest call, I asked them “do I sound like the person they’re looking for?” (a male) and I was told I should not answer my call this way, bare in mind they have called me 3 times today already. I asked the agent to remove my number and she answered with “No we will not and we will continue to call you.” This is honestly borderline harassment. Is it that difficult to comprehend that you have or were given the wrong contact number by the actual person you are looking for? Disgusting behavior from this company and its agents.
