Mothers details STILL incorrect.

Last year submitted the required request and ID document of my mother to get her details updated. Last week i recieved the annual portfolio summary in which my mothers details are still incorrect and for each of the policies, the initials are different. I sent a mail on thursday requesting that this be updated once again and till today,tuesday, I've recieved no response. Should I now pass away it would cause more issues for my family to claim as information on your side is incorrect and you guy are failing to update it as per my request for the second time now. Its been a year now! It seems this is the only way to get a response from you guys
