We have been waiting on a response from them, I send out an inquiry emails weeks ago for mistakes that they made on their side. They have removed the beneficiary used old residential address after we gave them a new one still, have updated my granmather and Aunt as MR. I have politely send them mails to all branches closer to me and head office. Krugersdorp Randfontein even Head office, no call center agent cares to call us back. We even went to the branch for assistance and we were told to email and call head office. I don't know what will happen if anything happens if they die, they show no care since when it is not their family members. Old Mutual will not be the only one taken to socials if anything happens to my family members, I will definitely drag them on socials
