Very bad service from FNB Fiduciary

I must say how dissatisfied of the quality of service my family is getting from FNB Fiduciary. It’s been Over 6months trying to get my Mother’s Estate Late Processed. The silence we recieving is too loud. Responding to emails is a basic function in corporate cycles. So if you can be mum like this when a client does a follow up, it shows that FNB does not take client serious. What is the point of us following up when there is going to be NO ACTION from your side. We were expecting an update from you after 21 day as per your promised, but that did not come through and I thought that I should give them time until 30 days (which is now coming Wednesday the 15th). My concern is most people are taking year end vacation and possibilities are, this matter will be shelved until next year when most people will be back in offices. Does this mean we must give up on quality service when it comes to FNB? FNB is such a disappointment really, even to their so call Private Client.
