FNB Fiduciary bad service

Hi there people if i could have giving 0 rating to FNB Fiduciary i would, but i wouldnt recomend any one to take out a trust by them, they dont have a care in the world they want to put me out in the street they handled my grandfathers estate after we said my grandmother will be the executor yet we didnt know we should get a letter of executorship by the high court after we asked them musnt we come to cape town they said no everything is in order they will sort out everything we were the ones keep mailing them how far things are then they just rep**** this and that needs to be done recently they send us documents saying the estate is insolvent but they never kept in touch saying that the estate might not cover everything then we could have made a plan now they want the cashfall amount in full or they going to sell the house to cover those debt and so we found out that my granny isnt the executor now we cant pay in installments and they just want the money if they would have kept in touch we would have known if they would have told us fam the estate is going to be sort i mean they working with it so they suppose to know but if it wasnt for us emailing asking how far things are we would have never known about this now they say asap it must be pay otherwise they will sell the house how cruel after they handled everything

Is there maybe advice on this or anything i can do to safe the house i cant make loans im under debt review please any advice because we stressed out
