BOMITAS REFUSES TO REFUND SAVINGS

I was with Bonitas until September 2024. The medical fund company has not refunded my savings money. I submitted my documents for my savings to be moved to my new medical aid, and just an ID copy. I was told to wait for 4months, I was suppose to recieve my savings money in February. I called in January, and agent said all my documents are fine and I will revieve my savings money on the 1st of February. I did not recieve my savings on the 1st of February, I called again in March and they said I should submit a certified ID copy nor older than 3months. They did not tell me this before, I however did submit a new certified ID copy, and still no payment. It's now 6months and what should I do? I need to use my savings money. Other colleagues have a similar problem too, where they are also given the run around instead of just refunding our savings.
