Fidelity Pension Fund Surplus

My father was traced by a company called the data factory around 2011, he was told he needs to claim his Fidelity Guards Pension Fund Surplus. He completed documents and couriered it to them as per their request. It's been handed over to Jennifer Damane from Absa. I've been given a client reference when speaking to her. But I cannot get hold of her. My dad has now passed and still nothing from Absa. I am assisting my mom in this matter to claim. Please can anyone help. Thank you.
