Bad behavior

I'm disappointed with Cindy Botma the Human Capital lady. My mother went for retirement last year in March 2020 and I have since made her aware that my mother's pension was paid from 1992 and she was appointed in 1983, according to the documents for claiming UIF she was registered in 1983 but the pension registered in 1992. I have went to the company several times, being sent from pillar to post without any help. I was very polite about the whole ordeal and decided to leave everything as it is. My mother decided to approach someone in the company and finally we got the information in September 27 2021 that she was previously under another pension fund with Another financial institution. I then called Cindy to request her to contact the financial institution to request the file just find out what happened to my mother's pension fund between 1983 and 1992. She was so rude to me and told me that my mother must do that on her own since she is no longer part of the company. I reported the mater to Vuyo because I was told he is the manager, Vuyo referred me to Marita who was not in the office. Cindy requested that I speak to Botsane the guy who works for the Union. At this moment no one has come back to me or my Mom. I want to know, does Interstate do this to its employees especially those who are illiterate. I requested to be connected to Mr Mokgothu, I'm still waiting. My mother has worked for her money and she must get it
