FNB poor service

I have a personal loan with FNB which I took in 2016 unfortunately I lost my job as I was a temp, I contacted them then I was asked to send documents as a proof that I am no longer working which I did & nothing was communicated with me, on my side I was paying a little amount of money as I was getting UIF then I battled to get a job I called them again last year I was asked to send an affidavit which I did then boom the account was handed to lawyers fine my partner helped me to make payments as this people were calling me 10 times a day so that at least the account can go back to fnb that's what those people told me unfortunately after paying that outstanding amount they still calling me to remind me about the payment. I told them that I am still not working they asked me to send the documents which I did (send them to the lawyers & fnb claims) no one called me or what so ever fine I had to follow up then they telling me that fnb wants a retrenchment letter which I wont have as I was a temp. Now on Friday when I phoned fnb I was told that the insurance only pays once then they wont pay anything cause I was a temp. So I want to cancel that insurance as I will be paying for something useless that wont assist me in the future they have listed me I wanted to get some money somewhere so that I can settle the debt according to the system as still under last years errors which I paid by 2 months ago.
