Fnb do not want to help me. They put me in a difficult situation by taking my income

Hi I am a widow. My house was sold low beyond it's value. My agent arrange that the occupational rent will come to me directly, because I don't have an income at the moment. It is all in writing. Then fnb just instructed the transfer attorney that I cannot receive the occupational rent because of the exsess on the estate, but no one informed me or give me notice of this. I received an email on the first of Des. How must I pay rent and buy food? My elderly parents also live with me. I take care of them. Fnb cannot just break a written agreement, it's because of this agreement that I allowed the buyers to move in.. This is not fair. They can take the money from Jan 2024, even better we can arrange a payment plan, but they cannot just take my rent and food money without a decent notice to me. Now I. Am stuck I have to pay my rent and buy food. They cannot just break our written agreement. Please help me. The estate late Markus Joseph Grabie ***, the property rates have a shortfall because my agent did not work at least 3 months pro rata R, in for the rates. I was assured that the selling price will cover the important debt like the bond on the house, property rates, interest, at least otherwise I wouldn't have sold the house for that low price. I could move back myself and live there until transfer is complete without worrying about paying rent. What happened to fnb, how can we help you? What am I supposed to do now? Thank you Amelda Grabie
