Direct Recruiters Inc, Cleveland OH

I received a couple calls from "David". I had no interest, so I figured after two ignored called I wouldn't hear anything. Then I received a third call basically telling me unless I call him back, he would continue to bother me. I sent in an email asking them to leave me along, and he called a fourth time. If it appears as a person isn't interested, leave them along and don't harass them. Very unprofessional and annoying.
