Incompetence and incorrect information

I left my previous employment and asked that the money must be transferred to my new employer whose Provident Fund is also at Momentum - Funds at Work. I completed the required documents, but funds were not transferred. I instead today (26/3/2025) received DISTURBING correspondence stating that the money was paid to an account unknown to me with a tax certificate.?? I NEVER REQUESTED OR AUTHORISED THE MONEY TO BE PAID OUT. I submitted the choice for the money to be transferred. I received confirmation of receipt of my choice on 9 January 2025, but funds still do not reflect. Despite my choice, I received correspondence on the 14th of March stating that my choice was to withdraw the funds and that an application for a tax directive will be made. I then, on the same day rep**** that I don't want the money to be paid out but transferred and up to date, I received no reply except for the letter received today containing information unknown to me. I immediately contacted Momentum only to be advised that they "think" the money has been transferred to the fund of the new employer which is not the case. I was then assured that "somebody" will phone me which also never materialised.
