Failure to make monthly R1200 payment

I am so disappointment with the service that I am getting with Standard Bank funeral cover department. I am the beneficiary on my Mom's policy, NJ Mpolweni, ***. I submitted the claim in March and it was paid out except for the R1200 that I am suppose to be getting on the 1st of each month. since then, I have been calling Std bank every month and I only received the 1st payment last month. this month, August, nothing has been paid and I have been calling since the 5th August and there is still nothing with no explanation of what is happening, except being told that the payment was approved, but nothing was paid into my account.
