Certain friend in uncertain times- I think not

I've been trying to get an update from Old Mutual regarding a death claim. I sent an email to SARAF correspondence on Monday and I've been calling the call centre every day without any luck. No one ever answers the phone and I'll be on hold for 30 minutes at a time. It has been such a frustrating experience, losing a mother is hard enough but having deafening silence from a company she entrusted her pension to makes it all the more worse. Can someone please answer the phone or respond to my email?
