Removal of reference number for a deceased person

I am struggling to have my contact number removed for an employee that has put me up as a reference. I have now escalated this matter to Lindiwe M (given by Nqobile) to assist. It is very clear that all the assistance I have given MBD regarding this person (being deceased) have fallen on deaf ears. How difficult is it to remove my number that has no relevance to the person they are trying to contact.
