Inefficient and disinterested service from Link Investor Services

I am just so annoyed and disappointed with the lack of service, efficiency, care or follow up with regards to the transfer of my Uncles OM shares who is now overseas and in very ill health to my Step Mother who is also 80 and desperately needs the money.They have tried so many times to sort this out, phone, send fica and other POA docs etc but still no help or finalisation!!!??? I also have OM and Quilter shares phoned last week to try sort this all out as I have the relevant completed documents etc as I was in the UK with the MItchells over New Year. Tiffany answered the call ,last Thursday 13th Feb and promised to send me the relevant email iro my shares , I however am still waiting? Further she phoned after getting authorisation , my Step Mom Mrs Malvina Smit, in Jhbg and promised to resend her the email with the necessary forms which she previously had filled and sent but appears not on your system? The email too has still not been received? What goes on with the Link Services that everything is such a mission and so complicated. I truly am saddened after explaining the story to Tiffany whereupon she promised to assist yet has not. One would think we could rely on a company should as this but apparently not. I further phoned again today and left a message for a Senior / Supervisor to call me back however I am still waiting.
