MBD calls everyday looking for the wrong person

This people call me every day for the wrong person and when I say it's wrong number they just hang up. I try asking them to remove my number from this person's profile and they just hang up. Everyday while I'm working I must get calls looking for someone else and I have no idea why they have my number for this person. You can't tell me that you can't remove my number from this person's details!!!! It's beyond irritating already as I expect it to be a work call then it's MBD looking for the same person who is not me!
