Poor Service by Regent insurance

Submitted a claim for my late brother Kabelo Handsome Sakwane from Regent insurance company on 18/05/2018 where he had three 3 policies with them No: ********** ; ********** ; ********** then on 20/05/2018 i called Regent that's where I was told that policy No: ********** will not pay out as it was only a month of which i understand, & they're still processing the other two 2 policies it will only take 48hrs... on 22/05/2018 one 1 policy from the two 2 paid out R10-000 which was the funeral cover & one 1 did not pay, i called Regent on numerous times from that day till i decided to go to their offices in Bramfontein JHB where i was given a IL002 form that needs to be completed by his GP, i took the forms to the GP & emailed them as agreed communicating with Mbali Coka & Mabel Seweya on emails...till today the hundred thousand Rand R100-000 cover hasn't paid out for reasons unknown, the 48hrs plus more hours passed, had to make means for my brother to be buried on the 25/05/2018 & still there's no hope that Regent will pay
