Will I hear from Standard Trust Limited before I too am deceased?

Standard Trust Limited, who was the executor of my father's estate in 2017 and failed to transfer a motor vehicle into mother's name has proven impossible to get hold of either through the published email address or the ***number given to me by Standard Bank Deceased Estates department. My mother endured endless stress trying to resolve this matter and passed away in May 2022 without ever resolving it. I hope that I will hear from Standard Trust Limited having sent numerous emails over the past 3 months before I too am deceased. Rest assured my estate will not be handled by this group. I would hate for my next of kin to be dealt with in the same manner.
