Calls does not concern me

Good morning,<br> <br> I have been receiving calls from Nudebt since February 2015, every single time I ask them to remove my number from there system due to there calls don't concern me and on top of it all I supply them with the person regarding the call's number I have currently.<br> <br> All these calls are concerning my ex employees who worked with me in the past, I don't work with them anymore and all I'm asking is for Nudebt to remove my contact info from there system due to these calls are interfering with my current job.<br> <br> Regards
