Non service delivery

My father passed away and i put in a claim on behalf of my mother as she was the beneficiary. The claim paid out but what is still outstanding and we are yet to receive is the grocery benefit and tombstone contribution. Everytime i call into the customer care i get told different stories and empty promises being made. I am disappointed in the service received and quite shocked because i myself have a policy with standard bank. So my family will eventually go through the same hassle. I need this sorted out ASAP before i take it even further.
