Harassing people regarding dead people

Get your info updated! You keep on phoning me, sending me sms's regarding a lady that worked for my mother! My mother passed 3 years ago, and then the lady that worked for my mother, also passed about 6 months after my mother. Now you keep contacting me regarding the lady's account, want info of the deceased's family members and sending final notice via sms to my number? I have told the people that phoned me, she is deceased. I went to a store to contact h/o so that my number can be taken off, but now they want the account number from me??? Seriously? How must I know? I don't have any detail regarding this lady or her family - and I am not allowed to give out personal info without permission as per popi act - and yet still no satisfaction regarding this matter. Stop harassing me regarding a deceased person
