fnb and wesbank don't care

I had been banking with Fnb for over 15 years and I had a good business and during this period bought cars worth over 3 million and paid them all off and bought a house over 2million.2 years ago lost everything because of being de*****ed. Got q job and still made my repayments on time until i lost my job and I was continuously in contact with Fnb and wesbank regarding my accounts.but Ruthless ungrateful fnb who made millions from me from my business accounts and car and house loans decided to not assist me in any way I missed 2 payments only and they put me on blacklisting on it meant i could not get a job so how do i pay them even though I carried on paying after 3 months told them I would make up the arrears during this period I could not get a job as my credit checks were bad and I felt that Fnb charged me penalties and handover fees which I did not have. I feel that Fnb is ruthless heartless and only wants your money.but when you are down they kick you harder I hope Fnb and wesbank suffer a untimely death and the company is liquidated they don't deserve to exist.i have paid my arrears and up to date now yet they don't appreciate it.
