Incorrect IRP5 reference and poor customer service

I cashed out my retirement Annuity from Glacier by Sanlam. in October of 2023. Despite being notified that I am SARS emigrated and tax resident in another country, that has a Double Taxation agreement in place, Glacier proceeded to deduct tax from my payout. I now need to go through a process with SARS to complete my 2023/2024 tax return in order to request this tax to be refunded. When I finally received the IRP5 from Glacier and submitted this through E-Filing SARS rejected the IRP5 because the reference number on the IRP5 does not match the reference number SARS has on their system in respect receipts for my tax number from Glacier. I have been trying for over 6 months to get Glacier/Sanlam to correct this error - they are saying it is problem on SARS side and SARS says this is the information they received from Sanlam, and thus they need to correct this if their reference is incorrect. To Date I have been unable to get Glacier/Sanlam to sort this out. To make this problem even worse; I need a tax directive to move more than the annual allowance to get my retirement funds offs**** to reinvest in my new country. SARS will not issue this tax directive, because my tax return for 2023/2024 is now outstanding due to these erroneous taxes being paid over to SARS. So as the Rand/Euro deteriorates, and my money is in limbo (not invested and growing) I am losing and Sanlam/Glacier have ZERO interest in helping to resolve this issue as I have cashed out my retirement annuity.
