Keep getting calls for someone else

Everyday twice a day i keep getting calls for somones else debt. I have notified this lady countless times to stop calling as i do not live with that person that we not even in the same province but she keeps calling my number and asking for him. Just because im listed as a next of kin does not mean i have to be bothered everyday by this lady. I have given her your client wifes number but this idiot keeps calling me. Please remove my number off you system
