ABSA Funeral Cover

I app**** for funeral and life cover with ABSA online as I lived overseas. The first policy was opened on 01-04-2017. I made a mistake with my grandfathers year of birth, and requested an amendment. They told me that they are unable to do this on their system. But they WERE ABLE TO INCREASE THE MONEY I HAVE TO PAY FOR HIM. Upon realizing this, I requested an official letter stating all my beneficiaries and they still have not sent that. Instead I was told to open A SECOND FUNERAL POLICY (opened on 01-11-2017) WITH HIS CORRECT DATE OF BIRTH. I have done this, but I still have not received any letter confirming that I am covered. When I went back home to South Africa, I even called them at the Newcastle branch. They still have not called me back. I am concerned that I might not even be able to claim from both life covers even though I have been paying them for more than a year.
