Do not Trust Standard Trust services

We have enlisted the services of Standard Trust Services to assist with winding up the estate for my late grandmother in February 2020. We understand that there are delays with regards to the Master's Offices due to the rise in deaths relating to Covid over the last 2 years. However, we have been constantly following up on a monthly basis since 2020 and have been constantly told some or other excuse. We are now more than 2 years later and still no resolution. The person assigned to the case has since resigned without providing us details of the new person. I have tried getting hold of Ralda Buys who apparently has taken over but she doesn't respond to e-mails or return calls. I have then tried to get hold of Rentia who is apparently the team leader and still nothing. I then tried to get hold of the manager Danie Du Toit and he also does not return calls or respond to e-mails. We are now sitting with accounts to be paid from the Estate with no resolution or assistance from anyone at Standard Trust. The lack of service is absolutely horrific.
