Momentum Corporate refusing to Pay a Client Provident Fund

I am a Broker and I have a Client who retired in March 2025 and had her Provident Fund with Momentum Funds @ Work. She approached me and told me that she had been trying to get her money from Momentum since March 2025 without any success. She asked that I help her transfer the whole amount as she cannot deal with them anymore. We called them and informed them on 30 July 2025 and we waited for an ROT since then. I followed up and followed up and the Call Centre would tell me that the ROT was sent to me on Monday the 11th and it was not. It took 2 weeks to Recognise the Transfer and another week to finally send me the ROT which I only got on 15 August 2025. I made sure that I complete the ROT open my side and send it back SAME DAY, and since then the money is not coming out of Momentum Funds @ Work. So the Client is waiting for her provident Fund for 5 months and we still haven't received it. I don't know who to escalate to and when I call the Call Centre there, I cant be transferred to someone senior. Anyone with email addresses and numbers I could use? 5 MONTHS is not a joke trying to simply WITHDRAW your own money!
