Estates Department Service

I have been waiting for almost two (2] years for my mother's estate late account to be wound by the executor Radhika Sinayhakh and I am still waiting for this matter to be resolved. I am the one who always follows up and asks for information and going around to resolve the issues coming up in the matter, but shouldn't the person appointed as executor be doing all this ? This is their duty and they are the ones getting paid for it but I'm doing the work. Unless I initiate contact I am left without communication unless of course I don't give them something they suddenly desperately need for me then I'm at the top of the call list. I've lost my dad shortly after my mum and his estate is also at a standstill due this one moving slower than a snail pace. I wanted this to done by last year and at this point I don't know when I'll be able to see the completion of this matter
