They called today didn't say who they are just went to ask for somebody . They went on to ask for their number and where they are . I ask who they represent and wouldn't say . I went on who they are . They finally  said something which wasn't clear . I asked again and they say their a mediation company and again asked who they are and they told me . They're bill collectors who use illegal methods to collect . They are now blocked and if it happens again I will take action . DON'T pick up .
