Almost 3 years and my profile is not updated

I've been trying since 2019 to update my mobile number with Old Mutual in order for me to be able to log into their application and website to monitor the progress of my policies. Still, they have not done it. I've now requested Old Mutual to freeze my policy using the payment gap for the next 6 months and they don't acknowledge my request. If the account is not frozen as requested, be prepared for a big fight and refunding my money. I've also asked on several email who my new financial adviser is and it's also gone unanswered. I've messaged my previous old mutual advisor on Whatsapp, she also just read my message without replying.
