FNB institutes legal action unfairly!!!!

Were under debt review and voluntarily came off 2 years ago and started paying bond fully plus additional R2000. Arranged an agreement with FNB. After 2 years in which we never defaulted on the arrangement FNB reviewed us and without any explanation is demanding us to pay +- 280 000.00 over and above our monthly payments in the next two years. ( this outstanding money came from being on debt review)<br> Our financial situation has not changed and we are doing everything in our power to pay our bond first before anything else not to default on our arrangement with FNB yet they don't care and are instituting legal action and threatening the roof over our heads. I have begged and pleaded to take the outstanding money which was caused thru being on debt review over 6 year period which will be reachable for me financially but still they turn a blind eye.and decline every possible arrangement i try and make. They expect me to come up with 13000.00 extra a month over and above my monthly payments. I have stuck to my side and managed to pay +- 2000.00 extra every month for 2 years without fail and this is the reaction i get from FNB. It seems don't dare come off debt review or they will rep
