Old Mutual superfund

My dad sorted his claim with Old Mutual back in early December, thinking he'd see some action. But no, nothing. A whole month later, he treks back there, only to be told, 'Oh, some papers are missing.' So, he gets them, submits them, and what happens? Two months pass, and we're still in the dark. The last they told him was, 'You'll get your money in a few days,' but here we are, two months on, and not a peep from Old Mutual. If he's not blatantly being ignored, they're impatient with him asking questions about his money.

Honestly, Old Mutual is a disgrace. When your service is this bad, what's the next move? Because right now, I'm stuck between frustration and disbelief.
