INSURANCE POLICY UNPAID

I Mpho Nancy Mohlaloga have taken funeral cover insurance policy for my parents with Standard Bank on the 16th January 2010. When I app**** for the policy I did declared that my parents were divorced, and I did sent divorce papers accordingly. I am the account holder and also the payee of the monthly premium. My mother EM Mohlaloga is the main insured and my late father VW Mohlaloga was the insured. My father passed on the 23 November 2015, we log the claim on the 19th December 2015 at Standard Bank Pretoria branch. All required original documentation were submitted at the Pretoria branch Standard Bank. Later on the Standard Bank claiming department requested us to fax the marriage and divorce decree certificates. They were sent accordingly. Now the Bank is refusing to pay out the claim, and they can't even give the proper explanation for the repudiation. Since I have been waiting for them to explain what exactly that they are implying. I do not know if the person who assistant me still works for the company but her name is MC Mokgoko, I don't know if is possible to follow up with her in terms of the contract.
