Utterly poor service

Utter poor client service. I lost my job on 30 April 2019 after working for the company or ten years, contributing the whole time to the provident fund managed by Alexander Forbes.The company first had another financial company managing the fund, but later transferred the provident fund to Alexander Forbes. The dates on their online system is incorrect. I have requested several call backs, no reply. I have launched a complaint a week ago, no reply. The amount paid out is incorrect. The call center cannot view my information. This company has no regard for people. Please assist
