I will be sending corpse to Capitec till they pay me to bury my brother

So, I had joined capitec funeral plan 2018 because everything online and I love convenience. Everything went well so I thought till I ammended the policy in 2019, signature date as per contract is 19/11/2019. They deduct themselves ever since. I noticed change on my premium and connected it to the ammendment, fair enough. Until I had to claim. My brother committed suicide and that alone is traumatic for me. I went and submitted claim only to realise what they have on the system is totally different from what appears on the Legally binding contract we have. I noticed a discrepancy on the premium which is not my fault however was willing to top it up. On their system I am not in arrears but everything remains as initially was. I had changed my brother's cover (including others but this concerns my brother at this point) from R10 000 to R20 000. That is what the latest contract sent to me even at this point says. I narrated everything at the bank which was escalated.as I waited I called 2 times, 1st the call was hung in my ear and the other told me the policy was paid R9 800 and there's nothing she can do I should call complaints. I have not recieved any feedback regarding the mishap on the ammendment errors from their system vs my contract but was paid only R9800. I refuse to accept this. I need to bury my brother tomorrow and I am not leaving Newcastle branch until this is sorted. My incident number is ***7 and 83 44 85 11 respectively. My policy number is CF***3 I have both former and current contract which I was sent my official capitec. There's nowhere to take the corpse until I pay the Funeral Parlor. I will resort to sitting with my brother's corpse till I get paid my R20 000. I am so frustrated and I refuse to be treated like this.
