Poor customer service

I'm launching this complain on behalf of old mutual's poor customer service I've experienced. I'm an employee whose interested in claiming/ withdrawing on my two pot system to which I requested the claims via WhatsApp, but the process was unsuccessful due to my un-updated personal information in which I resorted to do that update via old mutual website/ app several times but still was unsuccessful. Then I went to the nearest branch for assistance and was given a phone to call the relevant consultant but still was unsuccessful due to my unanswered call. I sent an email they responded in asking for my personal details to which I provided and in return was told to submit my application that I don't even know about. I called the relevant consultant & refered the call to other department but still didn't receive any relevant assistance. I'm so very disappointed in old mutual customer service.
