Horrible service

I am highly disappointed at the service I have encountered with Sanlam corporate. I understand that there is the two pot queries that they inundated with however it is no excuse to not attend to other queries. I have been unsuccessful in reaching them over WhatsApp, their call centre as well as emails. I have been told on X that my query has been escalated since last week and I have not received any feedback. It is disappointing that such a big company is unable to provide a very simple service such as updating ones details. Why should I shoot through hoops for such??
