USELESS SASSA / POSTBANK

My mom's Sassa Card is blocked due to the fact that she was in Frailcare since Covid (2020) and was not able to withdraw her grant every month. There is a large amount in the card, but the block on the card cannot be removed due to SASSA / Postbank trying to avoid so-called "*****". They issued her with the new Postbank card in January 2025, and she was able to withdraw her monthly grant in February, but since then the card was blocked. We have been trying since March 2025 to get this block removed. We took her to the SASSA offices twice and they just passed the buck and said they cannot do anything, we have to phone the number on card (Postbank) and send them all the necessary documents (ID, Copy of Sassa Card, contact details) for them to send us/her a link to click on to verify that she is the person the card belong to. BUT since April, when we first sent the documents, the e-mails are not even delivered to the e-mail address they provide, i.e. ********. Once they even gave us a person working in the ***** department's e-mail address, same story. Up to now we've received no response, no e-mail, no link, nothing. So what to do??? We have no idea as you can phone them until you're blue in the face and they still do NOTHING, no response, no assistance, and no MONEY!!! If anybody from SASSA or Postbank see this post, PLEASE ASSIST!!!
