Jumping through hoops for my own money.

I have been trying to withdraw the funds from my retirement annuity from Dec 2018 . I am living overseas and was asked to provide my ID, a Tax certificate, a completed form, a certificate of residency and the funds were not released. i then tried again in July 2021. I started the process from scratch, i have been asked to provide the withdrawal form, supporting documents, then i received an email saying it will be processed. then on the 10/9/21 i was asked to provide banking details, and ID number of which i did. They did not accept my South African bank account details as it was my business account. I then provided another account details and bank statement. Then again i was told it will be processed within 10 days. I then got asked for a copy of the card, front and back. i sent this. I was then asked again the next day for the front of the card. I was then told it was accepted and will be processed. Then i was asked to send another proof of address. they then confirmed the outstanding information was received and it will be processed within 10 days. I now receive another email to request another proof if identity. This is becoming ridiculous. They have been making me jump through hoops for money that belongs to me. My husband also had his RA money released and they didnt ask his for all this information, and to make matters worse, transferred the money into his brothers south african bank account. I find his service appalling. Please assist.
