ZERO STARS! 1 star is tooo much for momentum!

ZERO STARS! 1 star is tooo much for momentum! After a year and 3 months since my fathers passing who was an employee at transnet with a pension / retirement fund with momentum, On the 31st of October my 2 older siblings and myself received our beneficiary letters stating how much money we will be receiving as beneficiaries. My 2 younger siblings did not, after enquiring i was told that they will be receiving their communication the "Standard Trust". I followed up every week thereafter until December, I was told that we will not be dealing the people we have been dealing with but people from Joburg and standard trust. i Decided to email standard trust and stranderd trust says that they never received any money from Momentum. When i went back to the Administrators in Cpt we were initially dealing with , they said they will follow up with payments, since January. I then called the Momentum Customer care line , i was told a comment was made on the 7th by Bonani Moeng requesting documents, i then emailed Bonani asking what documents she is waiting on because we have sent everything to Gloria, Jeff and Nomathemba in Cpt offices. No response. No one is answering my call or emails at time point and time. My father past over a year 6 months ago. My younger brother need to register for school. I always thought so highly of momentum before this experience and treatment. Someone please help me i just want this nightmare over
