Disappointment with FNB claims department refusing to pay me

I have a home loan and morgage protection plan both with FNB, the retrenchment benefit is 12 months. May 2019 I was retrenched, submitted a claim with FNB, and it was approved, they have so far paid for 9 months with difficulties, I have to call and follow up everytime, most of their payments are late, I app**** for the first 6 months it was approved and paid, and again for the last 6 months and approved too, but only 3 months were paid from the last 6 months, so FNB still need to pay for the remaining 3 months, now they do not want to pay for my April bond they are telling me lots of different stories everytime I call, I do not know what to do now, everything has been a nightmare from the first benefit claim up to now, the bond account is in arrears. I’m in bad books with FNB bond department and others. I was even disqualified to get eBucks which was the reason why I decided to bank with FNB.
