Standard Bank *****ing money from my MOM!!!

My Father passed away 5 years ago, the estate was sorted by attorneys in Humansdorp, My Mother got her title acts of the house everything, but hear this out, The Access Bond under my father name has never been closed by the Attorneys or the Bank, even though my Dad has passed away and at time of his death the Access Bond was clear R0.00, So long story short for 3 years they have billed Admin fees and some other fee on the bond account, and my Mom as a good citizen paid it over as she thought its because the estate has not been finished. But NOW 5 YEARS LATER BOND IS STILL OPEN HOUSE BEEN ON HER NAME FOR MORE THAN 3 YEARS BUT THE BOND ON DADS NAME IS STILL GOING STRONG. GONE INTO HUMANSDROP BRANCH, MANAGER SAID "Sorry nothing we can do phone head office, phoned head office o no nothing we can do phone lawyers they need to sort it out, its between them and bank, but in the mean time while nobody actually got a freaking cooking clue what they doing we must pay monthly fees for more than 5 years even though the account holder has passed away and the estate has been final and sorted out ages ago. So this here is bull, STANDARD BANK SOUTH AFRICA, I CAN GO AND DRAW R500 000 ON THE BOND, THE PERSON WHO THE BOND BELONGS TO IS DEAD..WHAT THEN???

YOU NEED TO CONTACT ME AND WE NEED TO SORT THIS OUT!!!! I am tiered, I am fed up and I will not pay one more sent for admin fees etc.
